Pull second round of input updates from Dmitry Torokhov:
 "A new driver for Weida wdt87xx touch controllers, and a bunch of
  fixups for other drivers"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: wdt87xx_i2c - add a scaling factor for TOUCH_MAJOR event
  Input: wdt87xx_i2c - remove stray newline in diagnostic message
  Input: arc_ps2 - add HAS_IOMEM dependency
  Input: wdt87xx_i2c - fix format warning
  Input: improve parsing OF parameters for touchscreens
  Input: edt-ft5x06 - mark as direct input device
  Input: use for_each_set_bit() where appropriate
  Input: add a driver for wdt87xx touchscreen controller
  Input: axp20x-pek - fix reporting button state as inverted
  Input: xpad - re-send LED command on present event
  Input: xpad - set the LEDs properly on XBox Wireless controllers
  Input: imx_keypad - check for clk_prepare_enable() error
