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

Pull HID fixes from Jiri Kosina: - a few fixes to Sony driver (rmmod breakage, spinlock initialization), by Antonio Ospite, Frank Praznik and Jiri Kosina - fix for wMaxInputLength handling regression in i2c-hid, by Seth Forshee - IRQ safety spinlock fix in sensor hub driver, by Srinivas Pandruvada - IRQ level sensitivity fix to i2c-hid to be compliant with the spec, by Mika Westerberg - a couple device ID additions piggy-backing on top of that * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid: HID: microsoft: Add ID for NE7K wireless keyboard HID: i2c-hid: Limit reads to wMaxInputLength bytes for input events HID: sony: fix uninitialized per-controller spinlock HID: sony: initialize sony_dev_list_lock properly HID: sony: Fix a WARNING shown when rmmod-ing the driver HID: sensor-hub: correct dyn_callback_lock IRQ-safe change HID: hid-sensor-hub: Correct documentation HID: saitek: add USB ID for older R.A.T. 7 HID: i2c-hid: The interrupt should be level sensitive HID: wacom: Add missing ABS_MISC event and feature declaration for 27QHD
