	Looks you have queued the patch into your tree, but just now I
	find the patch is not needed at all, since we have had

Preston Fick 7f482fc88a USB: cp210x: fix CP2104 baudrate usage
This fix changes the way baudrates are set on the CP210x devices from
Silicon Labs. The CP2101/2/3 will respond to both a GET/SET_BAUDDIV
command, and GET/SET_BAUDRATE command, while CP2104 and higher devices
only respond to GET/SET_BAUDRATE. The current cp210x.ko driver in
kernel version 3.2.0 only implements the GET/SET_BAUDDIV command.

This patch implements the two new codes for the GET/SET_BAUDRATE
commands. Then there is a change in the way that the baudrate is
assigned or retrieved. This is done according to the CP210x USB
specification in AN571. This document can be found here:
http://www.silabs.com/pages/DownloadDoc.aspx?FILEURL=Support%20Documents/TechnicalDocs/AN571.pdf&src=DocumentationWebPart

Sections 5.3/5.4 describe the USB packets for the old baudrate method.
Sections 5.5/5.6 describe the USB packets for the new method. This
patch also implements the new request scheme, and eliminates the
unnecessary baudrate calculations since it uses the "actual baudrate"
method.

This patch solves the problem reported for the CP2104 in bug 42586,
and also keeps support for all other devices (CP2101/2/3).

This patchfile is also attached to the bug report on
bugzilla.kernel.org. This patch has been developed and test on the
3.2.0 mainline kernel version under Ubuntu 10.11.

Grazvydas Ignotas 24307caef4 usb: musb: fix shutdown while usb gadget is in use
If we shutdown without stopping the gadget first or removing the cable,
gadget manages to configure itself again:

root@pandora /root# poweroff
The system is going down NOW!
Requesting system poweroff
[   47.714385] musb-hm halted.
[   48.120697]  gadget: suspend

[   48.290985]  gadget: notify connect false
[   48.295288]  gadget: notify speed 425984000

This is not only unwanted, it's also happening on half-unitialized
state, after musb_shutdown() has returned, which sometimes causes
hardware to fail to work after reboot. Let's better properly stop
gadget on shutdown too.

This patch moves musb_gadget_cleanup out of musb_free(), which has 2
callsites: probe error path and musb_remove. On probe error path it was
superflous since musb_gadget_cleanup is called explicitly there, and
musb_remove() calls musb_shutdown(), so cleanup will get called as before.

Sebastian Andrzej Siewior c74c930082 usb: gadget: check for streams only for SS udcs
Currently the UASP gadget fails to bind on an UDC which does not provide
stream support. This is true for all udc in tree except for dummy and
dwc3 since they don't support SuperSpeed.
There is no need to test for the availability of stream support on those
UDCs because we will never even try to use them. I think it is sane to
assume that StreamSupport is always available on SuperSpeed since it is
one of the key features.
The host side will only allocate on SS so this part is also fine.

the Coverity Prevent checker currently flags a warning about possibly
uninitialized use of 'ret' i usbhsg_recip_run_handle(). It does this
since it assumes we take one of the non-default branches in the switch
and then subsequently take the false branch in the 'if (func)' case
below. This exact scenario will never happen, but Coverity can't see
that for some reason. This patch initializes 'ret' to '0' when it is
declared which should shut up this report and won't really hurt - so
why not? At least then it's clear that 'ret' is always initialized..

Rusty Russell 90ab5ee941 module_param: make bool parameters really bool (drivers & misc)
module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

Sarah Sharp d0cd5d482b xhci: Fix USB 3.0 device restart on resume.
The xHCI hub port code gets passed a zero-based port number by the USB
core.  It then adds one to in order to find a device slot by port number
and device speed by calling xhci_find_slot_id_by_port.  That function
clearly states it requires a one-based port number.  The xHCI port
status change event handler was using a zero-based port number that it
got from find_faked_portnum_from_hw_portnum, not a one-based port
number.  This lead to the doorbells never being rung for a device after
a resume, or worse, a different device with the same speed having its
doorbell rung (which could lead to bad power management in the xHCI host
controller).

This patch should be backported to kernels as old as 2.6.39.

Al Viro 5b5f956035 functionfs: unfuck failure exits on mount
* if you do dput() of root dentry, do *not* follow that with iput() of root
inode.
* while we are at it, don't do that dput() at all - you are leaving the pointer
in ->s_root and your ->kill_sb() will be very unhappy with that.  It will do
proper dput(), though, so the easiest way is to leave that to it entirely.
* freeing ->s_fs_info is also best left to ->kill_sb() (which will do it
anyway), especially since we leave the pointer in place.
* that xchg() in ->kill_sb() is not a bug per se, but it's a plain and simple
masturbation with fewer excuses than Onan had...

Linus Walleij ee66e653ca mfd: Unify abx500 headers in mfd/abx500
This moves all the header files related to the abx500 family into
a common include directory below mfd. From now on we place any
subchip header in that directory. Headers previously in e.g.
<linux/mfd/ab8500/gpio.h> get prefixed and are now e.g.
<linux/mfd/abx500/ab8500-gpio.h>. The top-level abstract interface
remains in <linux/mfd/abx500.h>.

Julia Lawall e7c8e8605d drivers/usb/class/cdc-acm.c: clear dangling pointer
On some failures, the country_code field of an acm structure is freed
without freeing the acm structure itself.  Elsewhere, operations including
memcpy and kfree are performed on the country_code field.  The patch sets
the country_code field to NULL when it is freed, and likewise sets the
country_code_size field to 0.

Julia Lawall 5632c827cb drivers/usb/dwc3/dwc3-pci.c: introduce missing kfree
Glue needs to be freed on exiting the function in an error case.
Furthermore, pci, which is the first argument to the probe function should
not be freed before leaveing the function, as it is reused at the call
site.  So the free of pci is changed to free glue instead.

A simplified version of the semantic match that finds the problem is as
follows: (http://coccinelle.lip6.fr)

Janne Snabb 3c8c931671 usb: option: add ZD Incorporated HSPA modem
Add support for Chinese Noname HSPA USB modem which is apparently
manufactured by a company called ZD Incorporated (based on texts in the
Windows drivers).

This product is available at least from Dealextreme (SKU 80032) and
possibly in India with name Olive V-MW250. It is based on Qualcomm
MSM6280 chip.

I needed to also add "options usb-storage quirks=0685:7000:i" in modprobe
configuration because udevd or the kernel keeps poking the embedded
fake-cd-rom which fails and causes the device to reset. There might be
a better way to accomplish the same. usb_modeswitch is not needed with
this device.

Felipe Balbi 18b7ede5f7 usb: ch9: fix up MaxStreams helper
According to USB 3.0 Specification Table 9-22, if
bmAttributes [4:0] are set to zero, it means "no
streams supported", but the way this helper was
defined on Linux, we will *always* have one stream
which might cause several problems.

For example on DWC3, we would tell the controller
endpoint has streams enabled and yet start transfers
with Stream ID set to 0, which would goof up the host
side.

While doing that, convert the macro to an inline
function due to the different checks we now need.

Hans de Goede 71d85724bd xhci: Properly handle COMP_2ND_BW_ERR
I encountered a result of COMP_2ND_BW_ERR while improving how the pwc
webcam driver handles not having the full usb1 bandwidth available to
itself.

I created the following test setup, a NEC xhci controller with a
single TT USB 2 hub plugged into it, with a usb keyboard and a pwc webcam
plugged into the usb2 hub. This caused the following to show up in dmesg
when trying to stream from the pwc camera at its highest alt setting:

xhci_hcd 0000:01:00.0: ERROR: unexpected command completion code 0x23.
usb 6-2.1: Not enough bandwidth for altsetting 9

And usb_set_interface returned -EINVAL, which caused my pwc code to not
do the right thing as it expected -ENOSPC.

This patch makes the xhci driver properly handle COMP_2ND_BW_ERR and makes
usb_set_interface return -ENOSPC as expected.

This should be backported to stable kernels as old as 2.6.32.

When a host controller gives a bad event TRB, we should print out the

Sarah Sharp 79688acfb5 xhci: Be less verbose during URB cancellation.
With devices that can need up to 128 segments (with 64 TRBs per
segment), we can't afford to print out the entire endpoint ring every
time an URB is canceled.  Instead, print the offset of the TRB, along
with device pathname and endpoint number.

Only print DMA addresses, since virtual addresses of internal structures
are not useful.  Change the cancellation code to be more clear about
what steps of the cancellation it is in the process of doing (queueing
the request, handling the stop endpoint command, turning the TDs into
no-ops, or moving the dequeue pointers).

This bug seems to have been introduced by commit
d178bc3a70 "user namespace: usb: make usb
urbs user namespace aware (v2)"

I'm not sure if this is right fix, but it does stop the oops.

Unfortunately, the Point Grey software still refuses to work, but it's a
closed source app, so I can't fix it.
