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
