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
