HID: usbhid: Add support for SiGma Micro chip

2011-11-07T20:32:13+00:00

commit f5e4282586dc0c9dab8c7d32e6c43aa07f68586b upstream.

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.

HID: hidraw: fix window in hidraw_release

2011-01-07T22:43:13+00:00

commit cb174681a9ececa6702f114b85bdf82144b6a5af upstream.

[ Backport to .32.y by Antonio Ospite  ]

There is a window between hidraw_table check and its dereference.
In that window, the device may be unplugged and removed form the
system and we will then dereference NULL.

Lock that place properly so that either we get NULL and jump out or we
can work with real pointer.

HID: hidraw, fix a NULL pointer dereference in hidraw_write

2010-12-09T21:27:05+00:00

commit e42dee9a99a3ecd32b5c027e8f7411fb5bc11eb6 upstream.

BUG: unable to handle kernel NULL pointer dereference at 0000000000000028
IP: [] hidraw_write+0x3b/0x116 [hid]
[...]

This is reproducible by disconnecting the device while userspace writes
to dev node in a loop and doesn't check return values in order to exit
the loop.

HID: fix suspend crash by moving initializations earlier

2010-09-20T20:17:51+00:00

commit fde4e2f73208b8f34f123791e39c0cb6bc74b32a upstream.

Although the usbhid driver allocates its usbhid structure in the probe
routine, several critical fields in that structure don't get
initialized until usbhid_start().  However if report descriptor
parsing fails then usbhid_start() is never called.  This leads to
problems during system suspend -- the system will freeze.

This patch (as1378) fixes the bug by moving the initialization
statements up into usbhid_probe().

HID: usbhid: initialize interface pointers early enough

2010-09-20T20:17:51+00:00

commit 57ab12e418ec4fe24c11788bb1bbdabb29d05679 upstream.

Move the initialization of USB interface pointers from _start()
over to _probe() callback, which is where it belongs.

This fixes case where interface is NULL when parsing of report
descriptor fails.

HID: Add the GYR4101US USB ID to hid-gyration

2010-07-05T18:10:33+00:00

commit c2fd1a4ebf9127c280d227acb635eb1df213439c upstream.

This change adds in the USB product ID for the Gyration
GYR4101US USB media center remote control.  This remote
is similar enough to the other two devices that this driver
can be used without any other changes to get full support
for the remote.
