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: usbtouchscreen - support bigger iNexio touchscreens
Input: ads7846 - return error on regulator_get() failure
Input: twl4030-vibra - correct the power down sequence
Input: enable onkey driver of max8925
Input: use ABS_CNT rather than (ABS_MAX + 1)
