Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input fixes from Dmitry Torokhov: - a new product ID for the xpad joystick driver - fixes to resistive-adc-touch and snvs_pwrkey drivers - a change to touchscreen helpers to make clang happier * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: touchscreen - avoid bitwise vs logical OR warning Input: xpad - add support for another USB ID of Nacon GC-100 Input: resistive-adc-touch - fix division by zero error on z1 == 0 Input: snvs_pwrkey - add clk handling
