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

Pull input updates from Dmitry Torokhov:
 "Updates for the input subsystem.  You will get an new drivers for
  Hyper-V synthetic keyboard and for Neonode zForce touchscreens, plus a
  bunch of driver fixes and cleanups"
