* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
Input: appletouch - implement reset-resume logic
Input: i8042 - retry failed CTR writes when resuming
Input: i8042 - add Fujitsu-Siemens Amilo Pro V2030 to nomux table
Input: pcspkr - remove negative dependency on snd-pcsp
Manually fixed up trivial conflict in drivers/usb/core/quirks.c
