Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: gpio-keys - use IRQF_SHARED
  Input: winbond-cir - select LEDS_TRIGGERS
  Input: i8042 - try to get stable CTR value when initializing
  Input: atkbd - add a quirk for OQO 01+ multimedia keys
