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

Browse Source 
Pull more input updates from Dmitry Torokhov:

 - Apple SPI keyboard and trackpad driver for newer Macs

 - ALPS driver will ignore trackpoint-only devices to give the
   trackpoint driver a chance to handle them properly

 - another Lenovo is switched over to SMbus from PS/2

 - assorted driver fixups.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: alps - fix a mismatch between a condition check and its comment
  Input: psmouse - fix build error of multiple definition
  Input: applespi - remove set but not used variables 'sts'
  Input: add Apple SPI keyboard and trackpad driver
  Input: alps - don't handle ALPS cs19 trackpoint-only device
  Input: hyperv-keyboard - remove dependencies on PAGE_SIZE for ring buffer
  Input: adp5589 - initialize GPIO controller parent device
  Input: iforce - remove empty multiline comments
  Input: synaptics - fix misuse of strlcpy
  Input: auo-pixcir-ts - switch to using  devm_add_action_or_reset()
  Input: gtco - bounds check collection indent level
  Input: mtk-pmic-keys - add of_node_put() before return
  Input: sun4i-lradc-keys - add of_node_put() before return
  Input: synaptics - whitelist Lenovo T580 SMBus intertouch

Say Y here if you are running Linux on any Apple MacBook8,1 or later,
or any MacBookPro13,* or MacBookPro14,*.
You will also need to enable appropriate SPI master controllers:
spi_pxa2xx_platform and spi_pxa2xx_pci for MacBook8,1, and
spi_pxa2xx_platform and intel_lpss_pci for the rest.
To compile this driver as a module, choose M here: the
module will be called applespi.
