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

Pull HID fixes from Jiri Kosina:

 - functional regression fix for sensor-hub driver from Hans de Goede

 - stop doing device reset for i2c-hid devices, which unbreaks some of
   them (and is in line with the specification), from Kai-Heng Feng

 - error handling fix for hid-core from Gustavo A. R. Silva

 - functional regression fix for some Elan panels from Benjamin
   Tissoires

 - a few new device ID additions and misc small fixes

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid:
  HID: i2c-hid: Don't reset device upon system resume
  HID: sensor-hub: Restore fixup for Lenovo ThinkPad Helix 2 sensor hub report
  HID: core: fix NULL pointer dereference
