d526875deb Revert "usb-storage: implement autosuspend"
This reverts commit 8dfe4b1486.

There are a number of issues still remaining in usb-storage autosuspend,
so, to be safe, we need to revert this for now.

7d2c592609 USB: disable autosuspend by default for non-hubs
This patch (as965) disables autosuspend by default for all USB devices
other than hubs.  We are seeing too many devices that can't suspend or
resume properly, the blacklist is growing unreasonably quickly, and
this sort of thing should be handled in userspace.

drivers/usb/serial/bus.c: In function usb_serial_bus_deregister:
drivers/usb/serial/bus.c:185:
warning: passing argument 1 of free_dynids from incompatible pointer type

Above build warning comes when CONFIG_HOTPLUG=n because argument of
free_dynids() in serial/bus.c is a struct usb_serial_driver, not a
struct usb_driver. This is not a runtime bug, because the function
is an empty stub and never dereferences the passed pointer anyway.

49b4f90285 USB: fix serial gadget ACM breakage
Two of the CDC ACM control requests in the serial gadget have never
been correct, and have been reported to cause serious troubles ... as
in, soft lockup and maybe watchdog reset (depending on hardware).

This patch makes those request fail cleanly, rather than misbehaving.
Someone using CDC ACM should fix them according to the FIXME comments
which now replace the previous bugs.

c4766560e4 USB Mass Storage: limit "Rockchip ROCK MP3" device (071b:3203) max I/O to 64 sectors per command
The MP3/MP4/AVI player "Rockchip ROCK MP3" is seen as a USB disk, but fails
if more than 128 sectors (64kB) are sent or requested in a single read or write
command, and disconnects from the USB bus.

Typical kernel log showing the problem is:

usb 3-1: reset high speed USB device using ehci_hcd and address 6
usb 3-1: reset high speed USB device using ehci_hcd and address 6
sd 14:0:0:0: [sdb] Result: hostbyte=0x07 driverbyte=0x00
end_request: I/O error, dev sdb, sector 32
sd 14:0:0:0: [sdb] Result: hostbyte=0x07 driverbyte=0x00
end_request: I/O error, dev sdb, sector 32
usb 3-1: USB disconnect, address 6

This patch works around the device limitation by adding "Rockchip ROCK MP3"
to unusual USB devices list and limiting data transfers to 64 sectors (32kB)
per command.
Tested on 2.6.23-rc5 (amd64).

a78d702bee usb quirks: Add Canon EOS 5D (PC Connection mode) to the autosuspend blacklist
Recent versions of the Linux kernel auto-suspend attached USB devices.
After this happens to the Canon EOS 5D camera, the camera's interrupt endpoints
don't seem to wake back up correctly, causing further use with libgphoto2
to fail with a -114 "OS error in camera communication" error.

A similar fix is probably necessary for this camera in PTP mode, which
identifies as USB product id 0x3102, but we haven't tested this.

As part of our testing process, we tried the USB_QUIRK_RESET_RESUME
quirk also, it's not helpful in this case.

2f67cd5b1d usb-storage: fix bugs in the disconnect pathway
This patch (as961) fixes a couple of bugs in the disconnect pathway of
usb-storage.

The first problem, which apparently has been around for a while
although nobody noticed it, shows up when an aborted command is still
pending when a disconnect occurs.  The SCSI error-handler will
continue to wait in command_abort() until the us->notify completion is
signalled.  Thus quiesce_and_remove_host() needs to signal it.

The second problem was introduced recently along with autosuspend
support.  Since usb_stor_scan_thread() now calls
usb_autopm_put_interface() before exiting, we can't simply leave the
scanning thread running after a disconnect; we must wait until the
thread exits.  This is solved by adding a new struct completion to the
private data structure.  Fortuitously, it allows the removal of the
rather clunky mechanism used in the past to insure that all threads
have finished before the module is unloaded.

46dede4690 USB: accept 1-byte Device Status replies, fixing some b0rken devices
Some devices have a bug which causes them to send a 1-byte reply to
Get-Device-Status requests instead of 2 bytes as required by the
spec.  This doesn't play well with autosuspend, since we look for a
valid status reply to make sure the device is still present when it
resumes.  Without both bytes, we assume the device has been
disconnected.

Lack of the second byte shouldn't matter much, since the spec requires
it always to be equal to 0.  Hence this patch (as959) causes
finish_port_resume() to accept a 1-byte reply as valid.

c1f8ea7d35 USB: Support for the Evolution Scorpion robots
The attached (mostly trivial) patches adds support for the Evolution
Scorpion Robots.
  Evolution Robotics supplies a patch against 2.6.8 with their
software. My patch is based on their work, so I don't know if I can
sign it off, or if you need some Evolution people to do this (which
might be hard).
  The patch adds device ID's for some robots which is trivial.

It appears that one reason the "iConnect"-labeled multi-card reader was
on sale for only $5 is that it doesn't handle suspend/resume correctly.
Other than that, it was a good deal for a highspeed MMC/SD bridge.

468d13623b USB: serial: garmin_gps: fixes package loss if used from gpsbabel
This patch contains two fixes submitted by Ondrej Palkovsky:
- the 'ACK' packet is sent after the transfer of the USB packet is
completed, i.e. in the write_callback function. Because the close
function sends the 'abort' command, a parameter is added that allows
the caller of garmin_write_bulk to specify, if the 'ack' should be
propagated to the serial link or dimissed.
This fixes the problem with gpsbabel, it has sent several packets that
were acknowledged before they were sent to the GPS and GpsBabel closed
the device - thus effectively cancelled all outstanding requests in the
queue.
- removed the APP_RESP_SEEN and APP_REQ_SEEN flags and changed
them into counters. It evades USB reset of the gps on every device close.

This patch (as950) fixes a bug in the cdc-acm driver.  It doesn't keep
track of which interface (control or data) the sysfs attributes get
registered for, and as a result, during disconnect it will sometimes
attempt to remove the attributes from the wrong interface.  The
left-over attributes can cause a crash later on, particularly if the driver
module has been unloaded.

git commit b2bbb20b37 added direct
support for PXA GPIO D+ pullup as alternative to the older udc_command
ops method.  This was done by introduction of the pxa2xx_udc_mach_info
member "gpio_pullup" which, if initialized, is now used in (almost)
all places where udc_command used to be called.

This patch fixes two places where checks for availability of D+ pullup
control still only honor udc_command.

Update the scatterlist logic so that PIO options are also disabled
when an IOMMU may have coalesced pages during dma_map_sg() ... it's
not just HIGHMEM that can make trouble supporting both PIO and DMA
based host controller drivers.

There also seems to be a cross-arch issue here, with 64bit powerpc
not using an IOMMU define ... and its IOMMU_VMERGE config can always
be overridden on the kernel command line.  So this is better, but
still imperfect.

0d46c0079a USB: Remove pointless conditional in drivers/usb/serial/io_ti.c::edge_shutdown()
Coverity scan found (CID: 1708) this in
drivers/usb/serial/io_ti.c::edge_shutdown() :

...
2797 		for (i=0; i < serial->num_ports; ++i) {
2798 			edge_port = usb_get_serial_port_data(serial->port[i]);
2799 			edge_remove_sysfs_attrs(edge_port->port);
2800 			if (edge_port) {
2801 				edge_buf_free(edge_port->ep_out_buf);
2802 				kfree(edge_port);
2803 			}
2804 			usb_set_serial_port_data(serial->port[i], NULL);
2805 		}
...

It's complaining that we dereference 'edge_port' in line 2799 which
makes the test of that pointer against NULL in 2800 pointless, since if
edge_port was actually NULL we'd have crashed already before reaching
line 2800.
Reading the edge_open() function it seems to me that the pointer
returned by usb_get_serial_port_data(serial->port[i]) and stored in
'edge_port' can never actually be NULL here, so the test is entirely
superfluous (even if it could be NULL it would be pointless here,
ignoring the then possible crash in that case, since both
edge_buf_free() and kfree() can handle being passed NULL pointers.

This patch removes the pointless conditional (and also makes a few
tiny style corrections now that I was in the area anyway).

195af2cce5 USB: fix warning caused by autosuspend counter going negative
This patch (as937) fixes a minor bug in the autosuspend usage-counting
code.  Each hub's usage counter keeps track of the number of
unsuspended children.  However the current driver increments the
counter after registering a new child, by which time the child may
already have been suspended and caused the counter to go negative.
The obvious solution is to increment the counter before registering
the child.

69d42a78f9 USB: add "descriptors" binary sysfs attribute
This patch (as934) adds a new readonly binary sysfs attribute file
called "descriptors" for each USB device.  The attribute contains the
device descriptor followed by the raw descriptor entry (config plug
subsidiary descriptors) for the current configuration.

Having this information available in fixed-format binary makes life a
lot easier for user programs by avoiding the need to open, read, and
parse multiple sysfs text files.

The information in this attribute file is much like that in usbfs's
device file, but there are some significant differences:

	The 2-byte fields in the device descriptor are left in
	little-endian byte order, as they appear on the bus and
	in the kernel.

	Only one raw descriptor set is presented, that of the
	current configuration.

	Opening this file will not cause a suspended device to be
	autoresumed.

The last item in particular should be a big selling point for libusb,
which currently forces all USB devices to be resumed as it scans the
device tree.

1b4cd43bd3 isp116x-hcd: prepare for urb->status
This patch (as931b), adapted from a patch by Olav Kongas, makes a small
set of conservative changes to the isp116x-hcd driver in preparation
for the removal of urb->status.

	finish_request() is moved up in the source and is called
	as soon as the URB is known to have completed, rather than
	after all the active endpoints have been scanned.

	The status of a completed URB is kept in a local variable
	and copied to urb->status only when the URB is about to be
	given back.

	-EREMOTEIO error status for control transfers is set after
	the status stage rather than when the short packet arrives.

	Some unnecessary uses of urb->lock are removed.

I found the first regresson in the rewritten ("all dynamic" and "no races")
driver. If application uses O_NONBLOCK, I return -EAGAIN despite the URB
being submitted successfuly. This causes the application to resubmit the

The fix is to pretend that the transfer has succeeded even if URB was
merely queued. It is the same behaviour as with the old version.

aebdc3b450 dev_vdbg(), available with -DVERBOSE_DEBUG
This defines a dev_vdbg() call, which is enabled with -DVERBOSE_DEBUG.
When enabled, dev_vdbg() acts just like dev_dbg().  When disabled, it is a
NOP ...  just like dev_dbg() without -DDEBUG.  The specific code was moved
out of a USB patch, but lots of drivers have similar support.

That is, code can now be written to use an additional level of debug
output, selected at compile time.  Many driver authors have found this
idiom to be very useful.  A typical usage model is for "normal" debug
messages to focus on fault paths and not be very "chatty", so that those
messages can be left on during normal operation without much of a
performance or syslog load.  On the other hand "verbose" messages would be
noisy enough that they wouldn't normally be enabled; they might even affect
timings enough to change system or driver behavior.

8314418629 Freezer: make kernel threads nonfreezable by default
Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves.  This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.

It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.

The patch causes all kernel threads to be nonfreezable by default (ie.  to

655bfd7aeb backlight: Convert from struct class_device to struct device
Convert the backlight and LCD classes from struct class_device
to struct device since class_device is scheduled for removal.

One nasty API break is the backlight power attribute has had to be
renamed to bl_power and the LCD power attribute has had to be renamed
to lcd_power since the original names clash with the core. I can't see
a way around this.

c67ab134ba usb gadget stack: remove usb_ep_*_buffer(), part 2
This patch removes controller driver infrastructure which supported
the now-removed usb_ep_{alloc,free}_buffer() calls.

As can be seen, many of the implementations of this were broken to
various degrees.  Many didn't properly return dma-coherent mappings;
those which did so were necessarily ugly because of bogosity in the
underlying dma_free_coherent() calls ... which on many platforms
can't be called from the same contexts (notably in_irq) from which
their dma_alloc_coherent() sibling can be called.

The main potential downside of removing this is that gadget drivers
wouldn't have specific knowledge that the controller drivers have:
endpoints that aren't dma-capable don't need any dma mappings at all.

9d8bab58b7 usb gadget stack: remove usb_ep_*_buffer(), part 1
Remove usb_ep_{alloc,free}_buffer() calls, for small dma-coherent buffers.
This patch just removes the interface and its users; later patches will
remove controller driver support.

  - This interface is invariably not implemented correctly in the
    controller drivers (e.g. using dma pools, a mechanism which
    post-dates the interface by several years).

  - At this point no gadget driver really *needs* to use it.  In
    current kernels, any driver that needs such a mechanism could
    allocate a dma pool themselves.

Removing this interface is thus a simplification and improvement.

Note that the gmidi.c driver had a bug in this area; fixed.

Cleanups to the pxa2xx_udc code:

  - Primarily removing unused DMA hooks.
  - One "sparse" warning removed
  - Remove some Lubbock-only LED hooks (for debugging)

That DMA code was never really completed.  It worked, mostly, for IN
transfers (to the host) if they were fortuitously aligned, but that
code was never fully tested.  And it was never coded for OUT transfers
(which is where DMA would really help) ... because of chip errata on
essentially every chip other than the pxa255, and because of design
botches (nothing automated data toggle).  So it's effectively been
dead code for several years now ... no point in keeping it around.

fbf54dd320 USB: usb/dma doc updates
This patch updates some of the documentation about DMA buffer management
for USB, and ways to avoid extra copying.  Our understanding of the issues
has improved over time.

 - Most drivers should *avoid* the dma-coherent allocators.  There are
   a few exceptions (like the HID driver).

 - Some methods are currently commented out; it seems folk writing
   USB drivers aren't doing performance tuning at that level yet.

 - Just avoid highmem; there's no good way to pass an "I can do highmem
   DMA" capability through a driver stack.  This is easy, everything
   already avoids highmem.  But it'd be nice if x86_32 systems with much
   physical memory could use it directly with network adapters and mass
   storage devices.  (Patch, anyone?)

pillaging once again. The code is as streamlined as possible and is bug-free

abstract. The usblp is usb-skeleton which is actually used by many.

Since I combed a few small bugs away, this also fixes the small races we
had in usblp for a while. For example, now it's possible for several threads
to make write(2) calls (sounds silly, but consider a printer for paper
record, where every line of text is self-contained and thus it's all right
to have them interleaved). Also gone are issues with interrupts using
barriers dangerously.

to keep the bus busy for no good reason at all (this should be a power
savings.)

All in all, this saved over 40 lines of code and cleaned things up
better.

17c2327419 USB: sierra: remove incorrect usage of the urb status field
You can't rely on the fact that the status really is correct like it was.

Also simplified the write path and now we allocate the urb and data on
the fly, instead of trying to do that really odd timeout check which I
am guessing doesn't really work properly.  This should speed up the
device by keeping the hardware queue full easier.

As a benefit, this reduces the size of the driver.
