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

Pull HID updates from Jiri Kosina:
 "Some highlights:

   - hid-sony improvements of Sixaxis device support by Antonio Ospite
   - hid-hyperv driven devices can now be used as wakeup source, by
     Dexuan Cui
   - hid-lenovo driver is now more generic and supports more devices, by
     Jamie Lentin
   - hid-huion now supports wider range of tablets, by Nikolai
     Kondrashov
   - other various unsorted fixes and device ID additions"
