Pull HID updates from Jiri Kosina:
"Highlights:
- conversion of HID subsystem to use devm-based resource management,
from Benjamin Tissoires
- i2c-hid support for DT bindings, from Benjamin Tissoires
- much improved support for Win8-multitouch devices, from Benjamin
Tissoires
- cleanup of core code using common hidinput_input_event(), from
David Herrmann
- fix for bug in implement() access to the bit stream (causing oops)
that has been present in the code for ages, but devices that are
able to trigger it have started to appear only now, from Jiri
Kosina
- fixes for CVE-2013-2899, CVE-2013-2898, CVE-2013-2896,
CVE-2013-2892, CVE-2013-2888 (all triggerable only by specially
crafted malicious HW devices plugged into the system), from Kees
Cook
- hidraw oops fix, from Manoj Chourasia
- various smaller fixes here and there, support for a bunch of new
devices by various contributors"
