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: adds the context menu key (HUT GenDesc 0x84)
  Input: add definitions for frame forward and frame back keys
  Input: bf54x-keys - keypad does not exist on BF544 parts
  Input: gpio-keys - request and configure GPIOs
  Input: i8042 - add i8042.noloop quirk for MS Virtual Machine
  Sonypi: use synchronize_irq instead of sycnronize_sched
  sonypi: fit input devices into sysfs tree
  sony-laptop: fit input devices into sysfs tree
