Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid

Browse Source 
Pull HID subsystem updates from Jiri Kosina:
 "Apart from various driver updates and added support for a number of
  new devices (mostly multitouch ones, but not limited to), there is one
  change that is worth pointing out explicitly: creation of HID device
  groups and proper autoloading of hid-multitouch, implemented by Henrik
  Rydberg."
