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

Pull HID fixes from Jiri Kosina:

 - fix a small bug in computation of report size, which might cause some
   devices (Atmel touchpad found on the Samsung Ativ 9) to reject
   reports with otherwise valid contents

 - a few device-ID specific quirks/additions piggy-backing on top of it

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid:
  HID: sensor-hub: Add in quirk for sensor hub in Lenovo Ideapad Yogas
  HID: add NO_INIT_REPORTS quirk for Synaptics Touch Pad V 103S
  HID: core: fix computation of the report size
  HID: multitouch: add support of EliteGroup 05D8 panels
