Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov:
 "Mostly existing driver fixes plus a new driver for game controllers
  directly connected to Nintendo 64, and an enhancement for keyboards
  driven by Chrome OS EC to communicate layout of the top row to
  userspace"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (47 commits)
  Input: st1232 - fix NORMAL vs. IDLE state handling
  Input: aiptek - convert sysfs sprintf/snprintf family to sysfs_emit
  Input: alps - fix spelling of "positive"
  ARM: dts: cros-ec-keyboard: Use keymap macros
  dt-bindings: input: Fix the keymap for LOCK key
  dt-bindings: input: Create macros for cros-ec keymap
  Input: cros-ec-keyb - expose function row physical map to userspace
  dt-bindings: input: cros-ec-keyb: Add a new property describing top row
  Input: applespi - fix occasional crc errors under load.
  Input: applespi - don't wait for responses to commands indefinitely.
  Input: st1232 - add IDLE state as ready condition
  Input: zinitix - fix return type of zinitix_init_touch()
  Input: i8042 - add ASUS Zenbook Flip to noselftest list
  Input: add missing dependencies on CONFIG_HAS_IOMEM
  Input: joydev - prevent potential read overflow in ioctl
