Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input fixes from Dmitry Torokhov: "A few more fixes for the input subsystem: - restore naming for tsc2005 touchscreens as some userspace match on it - fix out of bound access in legacy keyboard driver - fixup in RMI4 driver Everything is tagged for stable as well" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: tsc200x - report proper input_dev name tty/vt/keyboard: fix OOB access in do_compute_shiftstate() Input: synaptics-rmi4 - fix maximum size check for F12 control register 8
