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: matrix_keypad - increase the limit of rows and columns
  Input: wacom - fix error path in wacom_probe()
  Input: ads7846 - check proper condition when freeing gpio
  Revert "Input: do not pass injected events back to the originating handler"
  Input: sysrq - rework re-inject logic
  Input: serio - clear pending rescans after sysfs driver rebind
  Input: rotary_encoder - use proper irqflags
  Input: wacom_w8001 - report resolution to userland
