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: xpad - add USB-ID for PL-3601 Xbox 360 pad Input: cy8ctmg100_ts - signedness bug Input: elantech - report position also with 3 fingers Input: elantech - discard the first 2 positions on some firmwares Input: adxl34x - do not mark device as disabled on startup Input: gpio_keys - add hooks to enable/disable device Input: evdev - rearrange ioctl handling Input: dynamically allocate ABS information Input: switch to input_abs_*() access functions Input: add static inline accessors for ABS properties
