Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid
Pull HID fixes from Jiri Kosina:
"Bugfixes for HID subsystem that should go in 4.1. Important
highlights:
- the patch that extended support for HID++ protocol for TK820
touchpad turns out to be causing regressions due to firmware
issues; patch reverting back to basic support from Benjamin
Tissoires
- Wacom driver can oops for devices that report non-touch data on
touch interfaces. Fix from Ping Cheng
- gpiolib is not mandatory for i2c-hid, so the driver shouldn't fail
if gpiolib is not enabled. Fix from Mika Westerberg"
