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

Pull HID fixes from Jiri Kosina:

 - fixes for a couple potential memory corruption problems (the HW would
   have to be manufactured to be deliberately evil to trigger those)
   found by Ben Hawkes
 - fix for potential infinite loop when using sysfs interface of
   logitech driver, from Simon Wood
 - a couple more simple driver fixes

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid:
  HID: fix a couple of off-by-ones
  HID: logitech: perform bounds checking on device_id early enough
  HID: logitech: fix bounds checking on LED report size
  HID: logitech: Prevent possibility of infinite loop when using /sys interface
  HID: rmi: print an error if F11 is not found instead of stopping the device
  HID: hid-sensor-hub: use devm_ functions consistently
  HID: huion: Use allocated buffer for DMA
  HID: huion: Fail on parameter retrieval errors
