Pull input updates from Dmitry Torokhov:
 "A fix for a panic in gpio-keys driver when set up with absolute
  events, a fixup to the new zforce driver and a new keycode definition"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: allocate absinfo data when setting ABS capability
  Input: define KEY_WWAN for Wireless WAN
  Input: zforce - fix possible driver hang during suspend
