Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid
Pull HID update from Jiri Kosina:
- Wacom driver fixes/updates (device name generation improvements,
touch ring status support) from Jason Gerecke
- T100 touchpad support from Hans de Goede
- support for batteries driven by HID input reports, from Dmitry
Torokhov
- Arnd pointed out that driver_lock semaphore is superfluous, as driver
core already provides all the necessary concurency protection.
Removal patch from Binoy Jayan
- logical minimum numbering improvements in sensor-hub driver, from
Srinivas Pandruvada
- support for Microsoft Win8 Wireless Radio Controls extensions from
João Paulo Rechi Vita
- assorted small fixes and device ID additions
