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

Pull HID fixes from Jiri Kosina:

 - Wacom driver functional and regression fixes from Jason Gerecke

 - race condition fix in usbhid, found by syzbot and fixed by Alan Stern

 - a few device-specific quirks and ID additions

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/hid/hid:
  HID: quirks: Add HID_QUIRK_NO_INIT_REPORTS quirk for Dell K12A keyboard-dock
  HID: mcp2221: add gpiolib dependency
  HID: i2c-hid: reset Synaptics SYNA2393 on resume
  HID: wacom: Report 2nd-gen Intuos Pro S center button status over BT
  HID: usbhid: Fix race between usbhid_close() and usbhid_stop()
  Revert "HID: wacom: generic: read the number of expected touches on a per collection basis"
  HID: alps: ALPS_1657 is too specific; use U1_UNICORN_LEGACY instead
  HID: alps: Add AUI1657 device ID
  HID: logitech: Add support for Logitech G11 extra keys
  HID: multitouch: add eGalaxTouch P80H84 support
  HID: wacom: Read HID_DG_CONTACTMAX directly for non-generic devices
