This patch (as1155) fixes a bug in usbcore. When interfaces are
deleted, either because the device was disconnected or because of a
configuration change, the extra attribute files and child endpoint
devices may get left behind. This is because the core removes them
before calling device_del(). But during device_del(), after the
driver is unbound the core will reinstall altsetting 0 and recreate
those extra attributes and children.
The patch prevents this by adding a flag to record when the interface
is in the midst of being unregistered. When the flag is set, the
attribute files and child devices will not be created.

need to remember to evict file from fasync lists; forgetting that

So let's keep our lives simple - let __fput() check FASYNC in

This patch (as1153) fixes a potential problem in hub initialization.
Starting in 2.6.28, initialization was split into several tasks to
help speed up booting. This opens the possibility that the hub may be
autosuspended before all the initialization tasks can complete.
Normally that wouldn't matter, but with incomplete initialization
there is a risk that the hub would never autoresume -- especially if
devices were plugged into the hub beforehand. The solution is a
simple one-line change to suppress autosuspend until the
initialization is finished.

This patch (as1151) protects usbcore against drivers that try to
unlink an URB after the URB's device or bus have been removed. The
core does not currently check for this, and certain drivers can cause
a crash if they are running while an HCD is unloaded.
Certainly it would be best to fix the guilty drivers. But a little
defensive programming doesn't hurt, especially since it appears that
quite a few drivers need to be fixed.
The patch prevents the problem by grabbing a reference to the device
while an unlink is in progress and using a new spinlock to synchronize
unlinks with device removal. (There's no need to acquire a reference
to the bus as well, since the device structure itself keeps a
reference to the bus.) In addition, the kerneldoc is updated to
indicate that URBs should not be unlinked after the disconnect method
returns.

This patch (as1152) may help prevent some problems associated with the
new policy of unbinding drivers that don't support suspend/resume or
pre_reset/post_reset. If for any reason the resume or reset fails, and
the device is logically disconnected, there's no point in trying to
rebind the driver. So the patch checks for success before carrying
out the unbind/rebind.
There was a report from one user that this fixed a problem he was
experiencing, but the details never became fully clear. In any case,
adding these tests can't hurt.

To modify the data value and length in the function of
usb_stor_huawei_e220_init in initializers.c That's because based on the USB
standard, while sending SET_FETURE_D to the device, it requires the
corresponding data to be zero, and its sending length also must be zero. In
our old solution, it can be compatible with our WCDMA data card devices, but
can not support our CDMA data card devices. But in this new solution, it can

This patch (as1149) fixes an obscure problem in OHCI polling. In the
current code, if the RHSC interrupt status flag turns on at a time
when RHSC interrupts are disabled, it will remain on forever:
The interrupt handler is the only place where RHSC status
gets turned back off;
The interrupt handler won't turn RHSC status off because it
doesn't turn off status flags if the corresponding interrupt
isn't enabled;
RHSC interrupts will never get enabled because
ohci_root_hub_state_changes() doesn't reenable RHSC if RHSC
status is on!
As a result we will continue polling indefinitely instead of reverting
to interrupt-driven operation, and the root hub will not autosuspend.
This particular sequence of events is not at all unusual; in fact
plugging a USB device into an OHCI controller will usually cause it to
occur.
Of course, this is a bug. The proper thing to do is to turn off RHSC
status just before reading the actual port status values. That way
either a port status change will be detected (if it occurs before the
status read) or it will turn RHSC back on. Possibly both, but that
won't hurt anything.
We can still check for systems in which RHSC is totally broken, by
re-reading RHSC after clearing it and before reading the port
statuses. (This re-read has to be done anyway, to post the earlier
write.) If RHSC is on but no port-change statuses are set, then we
know that RHSC is broken and we can avoid re-enabling it.

file returns true if an interface driver's .supports_autosuspend flag is
set. It also returns true if the interface is unclaimed (since the USB
core will autosuspend a device if an interface is not claimed).
This new sysfs file will be useful for user space scripts to test whether
a USB device correctly auto-suspends.

This patch (as1147) fixes the remote-wakeup support for EHCI
controllers using the ARC/TDI "embedded-TT" core. These controllers
turn off the RESUME bit by themselves when a port resume is complete;
hence we need to keep separate track of which ports are suspended or
in the process of resuming.
The patch also makes a couple of small improvements in ehci_irq(),
replacing reads of the command register with the value already stored
in a local variable.

The kernel doc for usb_bulk_msg() says the timeout for a bulk message should be
specified in milliseconds. The ftdi-elan driver converts milliseconds to
jiffies before passing the timeout to usb_bulk_msg(). This is mostly harmless,
since it will just lead to very long timeouts, but was obviously not the intent
of the original author.

In case of error, the function isp1760_register returns an ERR
pointer, but never returns a NULL pointer. So after a call to this
function, a NULL test should be replaced by an IS_ERR test. Moreover,
we have noticed that:
(1) the result of isp1760_register is assigned through the function
pci_set_drvdata without an error test,
(2) if the call to isp1760_register fails, the current function
(isp1761_pci_probe) returns 0, and if it succeeds, it returns -ENOMEM,
which seems odd.
Thus, we suggest to move the test before the call to pci_set_drvdata
to correct (1), and to turn it into a non IS_ERR test to correct (2).
The semantic match that finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@bad_null_test@
expression x,E;
statement S1, S2;
@@
x = isp1760_register(...)
... when != x = E
* if (x == NULL)
S1 else S2
// </smpl>

ehci_watchdog will wake up CPU very frequently so that CPU
stays at C3 very short, average residence time is about 50
ms on Aspire One, but we expect it should be about 1 second
or more, so this kind of periodic timer is very bad for power
saving.
We can't remove this timer because of some bad USB controller
chipset, but at least we should reduce its side effect to as
possible as low.
This patch can make CPU stay at C3 longer, average residence time
is about twice as long as original.
Please consider to apply it, thanks

This patch (as1140) adds a little intelligence to the interrupt-URB
scheduler in uhci-hcd. Right now the scheduler is stupid; every URB
having the same period is assigned to the same slot. Thus a large
group of period-N URBs can fill their slot and cause -ENOSPC errors
even when all the lower-period slots are empty.
With the patch, if an URB doesn't fit in its assigned slot then the
scheduler will try using lower-period slots. This will provide
greater flexibility. As an example, the driver will be able to handle
more than just three or four mice, which the current driver cannot.

Bugfix for the new CDC Ethernet code: as part of activating the
network interface's USB link, make sure its link management code
knows whether the interface is open or not.
Without this fix, the link won't work right when it's brought up
before the link is active ... because the initial notification it
sends will have the wrong link state (down, not up). Makes it
hard to bridge these links (on the host side), among other things.

Minor musb_hdrc updates:
- so it'll build on DaVinci, given relevant platform updates;
* remove support for an un-shipped OTG prototype
* rely on gpiolib framework conversion for the I2C GPIOs
* the <asm/arch/hdrc_cnf.h> mechanism has been removed
- catch comments up to the recent removal of the per-SOC header
with the silicon configuration data;
- and remove two inappropriate "inline" declarations which
just bloat host side code.
There are still some more <asm/arch/XYZ.h> ==> <mach/XYZ.h>

checking if speed asked for was USB_LOW_SPEED upon
usb_gadget_register() to deny service, it checked only
