Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input update from Dmitry Torokhov:
"Updates for the input subsystem. Just a couple of driver fixes this
time."
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
Input: gpio_keys - defer probing if GPIO probing is deferred
Input: gpio_keys_polled - defer probing if GPIO probing is deferred
Input: sentelic - only report position of first finger as ST coordinates
