3989ef6cfb HID: wiimote: Simplify synchronization
The new locking scheme in HID core allows us to remove a bit of synchronization.
Since the HID layer acts synchronously we simply register input core last and
there are no synchonization issues anymore.
Also register sysfs files after that to simplify the code.

8d3bb23609 drm/ttm: ensure ttm for new node is bound before calling move_notify()
This was true for new TTM_PL_SYSTEM and new TTM_PL_TT cases, but wasn't
the case on TTM_PL_SYSTEM<->TTM_PL_TT moves, which causes trouble on some
paths as nouveau's move_notify() hook requires that the dma addresses be
valid at this point.

f5e4282586 HID: usbhid: Add support for SiGma Micro chip
Patch to add SiGma Micro-based keyboards (1c4f:0002) to hid-quirks.

These keyboards dont seem to allow the records to be initialized, and hence a
timeout occurs when the usbhid driver attempts to initialize them. The patch
just adds the signature for these keyboards to the hid-quirks list with the
setting HID_QUIRK_NO_INIT_REPORTS. This removes the 5-10 second wait for the
timeout to occur.

74ad60292b usb/isp1760: Clear TT buffer on interrupted low & full speed transfers
When a low or full speed urb in progress is unlinked (or some other error
occurs), the buffer in the transaction translator (part of the hub) might end
up in an inconsistent state. This can make all further low and full speed
transactions fail, unless the buffer is cleared.

The bug can be seen when running the usbtest unlink tests as "set altsetting
to 0 failed, -110", and gets fixed by this patch.

da4fc14c99 s3c-hsudc: Fix possible nullpointer dereference during probe
The usb-interrupt is requested before the endpoints are initalised.
If an interrupt happens in the time between request_irq and the init
of the endpoint-data (as seen on the Qisda ESx00 ebook-platforms),
it is therefore possible for the interrupt handler to access endpoint-
data before its creation resulting in a null-pointer dereference.

This patch simply moves the irq request below the endpoint init.

72246da40f usb: Introduce DesignWare USB3 DRD Driver
The DesignWare USB3 is a highly
configurable IP Core which can be
instantiated as Dual-Role Device (DRD),
Peripheral Only and Host Only (XHCI)
configurations.

Several other parameters can be configured
like amount of FIFO space, amount of TX and
RX endpoints, amount of Host Interrupters,
etc.

The current driver has been validated with
a virtual model of version 1.73a of that core
and with an FPGA burned with version 1.83a
of the DRD core. We have support for PCIe
bus, which is used on FPGA prototyping, and
for the OMAP5, more adaptation (or glue)
layers can be easily added and the driver
is half prepared to handle any possible
configuration the HW engineer has chosen
considering we have the information on
one of the GHWPARAMS registers to do
runtime checking of certain features.

More runtime checks can, and should, be added
in order to make this driver even more flexible
with regards to number of endpoints, FIFO sizes,
transfer types, etc.

While this supports only the device side, for
now, we will add support for Host side (xHCI -
see the updated series Sebastian has sent [1])
and OTG after we have it all stabilized.

e879990604 USB: EHCI: remove usages of hcd->state
This patch (as1483) improves the ehci-hcd driver family by getting rid
of the reliance on the hcd->state variable.  It has no clear owner and
it isn't protected by the usual HCD locks.  In its place, the patch
adds a new, private ehci->rh_state field to record the state of the
root hub.

Along the way, the patch removes a couple of lines containing
redundant assignments to the state variable.  Also, the QUIESCING
state simply gets changed to the RUNNING state, because the driver
doesn't make any distinction between them.

0278ccd9d5 firewire: sbp2: fix panic after rmmod with slow targets
If firewire-sbp2 starts a login to a target that doesn't complete ORBs
in a timely manner (and has to retry the login), and the module is
removed before the operation times out, you end up with a null-pointer
dereference and a kernel panic.

[SR:  This happens because sbp2_target_get/put() do not maintain
module references.  scsi_device_get/put() do, but at occasions like
Chris describes one, nobody holds a reference to an SBP-2 sdev.]

This patch cancels pending work for each unit in sbp2_remove(), which
hopefully means there are no extra references around that prevent us
from unloading. This fixes my crash.

6d50c60e6d usb/isp1760: Use polling instead of SOF interrupts to fix Errata 2
Errata 2 for the isp1760 explains that the chip sometimes does not issue
interrupts when an ATL (bulk or control) transfer is completed. There are
several issues with the current work-around (SOF interrupts) for this:

1) It seems the chip sometimes does not even set the done bit for a
   completed transfer, in which case SOF interrupts does not solve
   the problem since we still check the done map to find out which
   transfer descriptors to handle.

2) The above point seems to happen only when ATL and SOF interrupts
   are enabled at the same time. However, disabling ATL interrupts
   increases the latency between transfer completion and handling.
   This is very noticeable in the testusb suite, which take several
   minutes more to run with ATL interrupts disabled.

This patch removes the code to switch on SOF interrupts, and instead
use a kernel timer to periodically check for "old" descriptors that
have their VALID and ACTIVE flags unset, indicating completion, thus
avoiding the dependency on the chip's done map (and SOF interrupts)
to find transfers affected by this HW bug.

f02fe890ec usb_storage: Don't freeze in usb-stor-scan
Scanning cannot be run during suspend or hibernation, but if
usb-stor-scan freezes another thread waiting on scanning to
complete may fail to freeze.

However, if usb-stor-scan is left freezable without ever actually
freezing then the freezer will wait on it to exit, and threads
waiting for scanning to finish will no longer be blocked. One
problem with this approach is that usb-stor-scan has a delay to
wait for devices to settle (which is currently the only point where
it can freeze). To work around this we can request that the freezer
send a fake signal when freezing, then use interruptible sleep to
wake the thread early when freezing happens.

To make this happen, the following changes are made to
usb-stor-scan:

 * Use set_freezable_with_signal() instead of set_freezable() to
   request a fake signal when freezing

 * Use wait_event_interruptible_timeout() instead of
   wait_event_freezable_timeout() to avoid freezing

b6bede3b4c xfs: fix tracing builds inside the source tree
The code really requires the current source directory to be in the
header search path.  We already do this if building with an object
tree separate from the source, but it needs to be added manually
if building inside the source.  The cflags addition for it accidentally
got removed when collapsing the xfs directory structure.

ab8ba3a2d2 serial: 8250_pnp: add Intermec CV60 touchscreen device
It would have been nice if Intermec had supplied a PNP0501 _CID for the
COM3 device, but they didn't, so we have to recognize it explicitly.

6c4b47d243 pch_uart: Set PCIe bus number using probe parameter
Currently, PCIe bus number is set as fixed value "2".
However, PCIe bus number is not always "2".
This patch sets bus number using probe() parameter.

651d62a8b0 drivers:misc: ti-st: fix unexpected UART close
If suppose the UIM were to die and hence UART were to close when the
Bluetooth/FM or GPS is turned on, prep the ST for a state where-in if
the UIM comes back up, Bluetooth/FM/GPS can be turned on.

76ff0e64d4 drivers:misc: ti-st: free skb on firmware download
If during validation of the firmware download the data doesn't match what is
expected out of the chip, this calls for a firmware download failure and a
retry.
Free the SKB which collects response during such scenarios.

2f81a02ce0 drivers:misc: ti-st: reinit completion before send
download firmware behaves differently at different times, when logs are
enabled and the system is loaded, the wait_for_completion is able to wait for
every send, However during other times the wait does not happen.

So, for reliability reinitializing the completion before every send, makes
sure the wait happens for every send.

78bb9697e2 drivers:misc: ti-st: fail-safe on wrong pkt type
Texas Instrument's shared transport driver interpret incoming data from the
UART based on the various protocol drivers registered to the driver such as
btwilink driver or FM or GPS driver which provide logical channel IDs.

In case of bad-behavior from chip such as HCI Event response for a GPS command
or a HCI Event (h/w error event) for a FM response & In case of bad-behavior
from UART driver such as dropping data bytes a fail-safe is required to avoid
kernel panic.

After the version information has been read, the completion which assists in
wait_for_completion during the firmware send/wait sequence is being re-used
and hence this needs to be re-initialised for fool proof firmware download
