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

Pull HID updates from Jiri Kosina:

 - patch series that ensures that hid-multitouch driver disables touch
   and button-press reporting on hid-mt devices during suspend when the
   device is not configured as a wakeup-source, from Hans de Goede

 - support for ISH DMA on Intel EHL platform, from Even Xu

 - support for Renoir and Cezanne SoCs, Ambient Light Sensor and Human
   Presence Detection sensor for amd-sfh driver, from Basavaraj Natikar

 - other assorted code cleanups and device-specific fixes/quirks
