HID: Add some missing HUT mappings

2015-07-30T12:10:56+00:00

commit 5820e4d4ae17c0994c93d0537bd1a184267f3cae upstream.

Add mapping for "AL Next Task/Application", "AL Previous Task/Application"
and "AL File Browser" buttons, as found on the Microsoft Office keyboard.

Note that there already is a mapping for "AL Local Machine Browser" to
KEY_FILE. Unless we ever encounter a device with both that should not be
a problem.

HID: hid-sensor-hub: fix sleeping function called from invalid context

2015-07-30T12:10:56+00:00

commit f74346a04b79c9a5e50a2ee5e923b94195975d17 upstream.

Fix issue with the sleeping calling hid_hw_request under spinlock.
When i2c is used as HID transport, this is calling kmalloc, which
can sleep. So remove call to this function while under spinlock.

HID: multitouch: add support for Win 8.1 multitouch touchpads

2015-07-30T12:10:55+00:00

commit 9abebedb123a577ecc5b69b2a2515499e430be24 upstream.

Multitouch touchpads built for Win 8.1 need to be sent an input mode feature report
in order to start reporting multitouch events. This is the same process sent
to Win 7 multitouch touchscreens except the value of the feature report is 3 for
touchpads.

HID: hyperv: make sure input buffer is big enough

commit 3ccfd0a8d7062a5590923578eea829ee582beba8 upstream.

We need at least HID_MAX_BUFFER_SIZE (4096) bytes as input buffer. HID
core depends on this as it requires every input report to be at least as
big as advertised.

ARM: shmobile: wait for MSTP clock status to toggle, when enabling it

2015-07-30T12:10:54+00:00

commit a028c6da34d434e35ba8322568c756ea97ff3c18 upstream.

On r-/sh-mobile SoCs MSTP clocks are used by the runtime PM to dynamically
enable and disable peripheral clocks. To make sure the clock has really
started we have to read back its status register until it confirms success.
