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

Pull input updates from Dmitry Torokhov:
 "The first round of updates for the input subsystem.

  Just new drivers and existing driver fixes, no core changes except for
  the new uinput IOCTL to allow userspace to fetch sysfs name of the
  input device that was created"
