Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid
Pull HID updates from Jiri Kosina:
- functionally equivalent cleanups for wacom driver, making the code
more readable, from Benjamin Tissoires
- a bunch of improvements and fixes for thingm driver from Heiner
Kallweit
- bugfixes to out-of-bound access for generic parsing functions (which
have been there since ever) extract() and implement(), from Dmitry
Torokhov
- a lot of added / improved device support in sony, wacom, microsoft,
multitouch and logitech driver, from various people
