commit b58af4066d240b18b43f202e07b9ec7461d90b17 upstream.
As David VomLehn points out, it was possible to receive an interrupt
before clearing the free-urb flag which could lead to the urb being
incorrectly marked as busy.
For the same reason, move tx_bytes accounting so that it will never be
negative.
Note that the free-flags set and clear operations do not need any
additional locking as they are manipulated while USB_SERIAL_WRITE_BUSY
is set.

commit b3e670443b7fb8a2d29831b62b44a039c283e351 upstream.
This patch fixes a race condition in two utility routines
related to the removal/unlinking of urbs from an anchor.
If two threads are concurrently accessing the same anchor,
both could end up with the same urb - thinking they are
the exclusive owner.
Alan Stern pointed out a related issue in
usb_unlink_anchored_urbs:
"The URB isn't removed from the anchor until it completes
(as a by-product of completion, in fact), which might not
be for quite some time after the unlink call returns.
In the meantime, the subroutine will keep trying to unlink
it, over and over again."

commit b6180ef7c99574c3350bbffa2a3a9d675321543d upstream.
This patch is to add a US Interface, Inc. "Navigator" USB device.
Specifically, it's a HAM Radio USB sound modem that also
incorporates three pairs of unique FTDI serial ports. The standard
Linux FTDI serial driver will only recognize the first two serial
ports of an unknown FDTI derived device and this patch adds in
recognition to these specific new IDs.

commit 0372a754be9aa43e19fd86c9bc04796d43b55e38 upstream.
This patch adds the product IDs of Huawei's K3765 and K4505 mobile
broadband usb modems to option.c. It also adds a quirk to the option
probe function so that binding to the device's network interface(class
0xff) is avoided. This is necessary to allow another driver to bind to
that, and to avoid programs like wvdial opening a nonfunctioning tty
during modem discovery.

commit afad19648f70c6493193e0a774bd754b7790b4a0 upstream.
I have added the ProductID=0xe729 VendorID=FTDI_VID=0x0403 which will
enable support for the Segway Robotic Mobility Platform (RMP200) in the
ftdi_sio kernel module. Currently, users of the Segway RMP200 must use
a RUN+="/sbin/modprobe -q ftdi-sio product=0xe729 vendor=0x0403 in a
udev rule to get the ftdi_sio module to handle the usb interface and
mount it on /dev/ttyXXX. This is not a good solution because some users
will have multiple USB to Serial converters which will use the ftdi_sio
module.

commit 33d973ad88ceb83ed1449592b7574b5b5bb33ac6 upstream.
Enlarging the buffer size via the MON_IOCT_RING_SIZE ioctl causes
general protection faults. It appears the culprit is an incorrect
argument to mon_free_buff: instead of passing the size of the current
buffer being freed, the size of the new buffer is passed.
Use the correct size argument to mon_free_buff when changing the size of
the buffer.

This patch (as1405) fixes a small bug in ehci-hcd's isochronous
scheduler. Not all EHCI controllers are PCI, and the code shouldn't
assume that they are. Instead, introduce a special flag for
controllers which need to delay iso scheduling for full-speed devices
beyond the scheduling threshold.

Commit 0ede76fcec5415ef82a423a95120286895822e2d, "USB: remove uses of
URB_NO_SETUP_DMA_MAP" introduced a regression by inadvertantly removing
initialization of the transfer flags. This caused initialization
failures in the ums-karma driver. Fix the regression by zeroing it.
While at it, as Alan Stern points out, the initializers for
actual_length and status are handled by the core and error_count
only matters for isochronous urbs, so they don't need to be set here.
Remove them.

The bmAttributes field of the SuperSpeed Endpoint Companion Descriptor has
different meanings, depending on the endpoint type. If the endpoint is
isochronous, the bmAttributes field is the maximum number of packets
within a service interval that this endpoint supports. If the endpoint is
bulk, it's the number of stream IDs this endpoint supports.
Only set the Mult field of the xHCI endpoint context using the
bmAttributes field if the endpoint is isochronous, and the device is a
SuperSpeed device.

When an attempt is made to read the interface strings of the Artisman
Watchdog USB dongle (idVendor:idProduct 04b4:0526) an error is written
to the dmesg log (uhci_result_common: failed with status 440000) and the
dongle resets itself, resulting in a disconnect/reconnect loop.
Adding the dongle to the list of devices in quirks.c, with the same
quirk Alan Stern's previous patch for the Saitek Cyborg Gold 3D
joystick, stops the device from resetting and allows it to be used with
no problems.

When a configured device is reset, the control endpoint's ring is reused.
If control transfers to the device were issued before the device is reset,
the dequeue pointer will be somewhere in the middle of the ring. If the
device is then issued an address with the set address command, the xHCI
driver must provide a valid input context for control endpoint zero.
The original code would give the hardware the original input context,
which had a dequeue pointer set to the top of the ring. This would cause
the host to re-execute any control transfers until it reached the ring's
enqueue pointer. When issuing a set address command for a device that has
just been configured and then reset, use the control endpoint's enqueue
pointer as the hardware's dequeue pointer.
Assumption: All control transfers will be completed or cancelled before
the set address command is issued to the device. If there are any
outstanding control transfers, this code will not work.

Without this fix, a USB 3.0 port is downgraded to full speed after a port
reset of a configured device. The USB 3.0 terminations will be disabled
permanently, and USB 3.0 devices will always enumerate as full speed
devices, until the host controller is unplugged (if it is an ExpressCard)
or the computer is rebooted.
Fajun Chen traced this traced the speed downgrade issue to the port reset
and the interpretation of port status in USB hub driver code. The hub
code was not testing for the port being a SuperSpeed port, and it fell
through to the else case of Full Speed.
The following patch adds SuperSpeed mapping from the port status, and
fixes the speed downgrade issue.

Commit 6c12db90f19727c76990e7f4801c67a148b30111 also seems to have
introduced a bug that is triggered when the command ring is about to wrap.
The inc_enq() function will not have moved the enqueue pointer past the
link TRB. It is supposed to be moved past the link TRB in prepare_ring(),
which should be called before a TD is enqueued. However, the
queue_command() function never calls the prepare_ring() function because
prepare_ring() is only supposed to be used for endpoint rings. That means
the enqueue pointer will not be moved past the link TRB, and will get
overwritten.
The fix is to make queue_command() call prepare_ring() with a fake
endpoint status (set to running). Then the enqueue pointer will get moved
past the link TRB.

On fsg_unbind the common->fsg pointer was not NULLed if the
unbound fsg_dev instance was the current one. As an effect,
the incorrect pointer was preserved in all further operations
which caused do_set_interface to reference an invalid region.
This commit fixes this by raising an exception in fsg_bind
which will change the common->fsg pointer. This also requires
an wait queue so that the thread in fsg_bind can wait till the
worker thread handles the exception.
This commit removes also a config and new_config fields of
fsg_common as they are no longer needed since fsg can be
used to determine whether function is active or not.
Moreover, this commit removes possible race condition where
the fsg field was modified in both the worker thread and
form various other contexts. This is fixed by replacing
prev_fsg with new_fsg. At this point, fsg is assigned only
in worker thread.

The full speed descriptors were copied to the usb_function structure
in the fsg_bind_config function before call to the usb_ep_autoconfig.
The usb_ep_autoconfig was called in fsg_bind using the original
descriptors. In effect copied descriptors were not updated.
This patch changes the copy full speed descriptors after the call to
usb_op_autoconfig is performed. This way, copied full speed
descriptors have updated values.

Setting MUSB Burst Mode 3 automatically enables support for
lower burst modes (BURST4, BURST8, BURST16 or bursts of unspecified
length). There is no need to set these burst modes based on the
packet size. Also enable the burst mode for both mode1 and mode0.
This is a fix for buggy hardware - having the lower burst modes
enabled can potentially cause lockups of the DMA engine used in
OMAP2/3/4 chips.

The new ulpi code defines fallback stubs for the Blackfin arch, but does
so incorrectly leading to a build failure:
drivers/usb/musb/musb_core.c:227: error: 'musb_ulpi_read' undeclared here (not in a function)
drivers/usb/musb/musb_core.c:228: error: 'musb_ulpi_write' undeclared here (not in a function)
Tweak the fallback stubs so that they do work as intended.

Attempt to build MUSB driver with CONFIG_PM=y (e.g. in the OTG mode) on DaVinci
results in these link errors:
drivers/built-in.o: In function `musb_restore_context':
led-triggers.c:(.text+0x714d8): undefined reference to
`musb_platform_restore_context'
drivers/built-in.o: In function `musb_save_context':
led-triggers.c:(.text+0x71788): undefined reference to
`musb_platform_save_context'
This turned out to be caused by commit 9957dd97ec5e98dd334f87ade1d9a0b24d1f86eb
(usb: musb: Fix compile error for omaps for musb_hdrc). Revert it, taking into
account the rename of CONFIG_ARCH_OMAP34XX into CONFIG_ARCH_OMAP3 (which that
commit fixed in a completely inappropriate way) and the recent addition of
OMAP4 support.

Commit 1c25fda4a09e8229800979986ef399401053b46e (usb: musb: handle irqs in the
order dictated by programming guide) forgot to get rid of the old 'STAGE0_MASK'
filter for calling musb_stage0_irq(), so now disconnect and suspend interrupts
are effectively ignored...

This patch (as1403) is a partial reversion of an earlier change
(commit 5f677f1d45b2bf08085bbba7394392dfa586fa8e "USB: fix remote
wakeup settings during system sleep"). After hearing from a user, I
realized that remote wakeup should be enabled during system sleep
whenever userspace allows it, and not only if a driver requests it
too.
Indeed, there could be a device with no driver, that does nothing but
generate a wakeup request when the user presses a button. Such a
device should be allowed to do its job.
The problem fixed by the earlier patch -- device generating a wakeup
request for no reason, causing system suspend to abort -- was also
addressed by a later patch ("USB: don't enable remote wakeup by
default", accepted but not yet merged into mainline). The device
won't be able to generate the bogus wakeup requests because it will be
disabled for remote wakeup by default. Hence this reversion will not
re-introduce any old problems.

Stanse found that sleep is called inside atomic context created by
lock_printer_io spinlock in several functions. It's used in process
context only and some functions sleep inside its critical section. As
this is not allowed for spinlocks, switch it to mutex.

Stanse found that isp1362_sw_reset tries to take a isp1362_hcd->lock,
but it is already held in isp1362_hc_stop. Avoid that by introducing
__isp1362_sw_reset which doesn't take the lock and call it from
isp1362_hc_stop. isp1362_sw_reset is then as simple as lock --
__isp1362_sw_reset -- unlock.

This patch corrects a problem with the merge of a previous
patch to add the CONTEC identifier.
I believe the merge problem occurred with the commit:
dee5658b482e9e2ac7d6205dc876fc11d4008138
Originally I submitted a patch and then they asked me to order the IDs
and resubmit, so did I. But unfortunately in the end somehow both
patches were merged.
