Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid
Pull HID fixes from Jiri Kosina:
- fixes for pen pen proximity / touch events in wacom driver, from Ping
Cheng and Benjamin Tissoires
- two new device-specific quirks from Oliver Neukum and Forest
Wilkinson
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid:
HID: wacom: check for wacom->shared before following the pointer
HID: tivo: enable all buttons on the TiVo Slide Pro remote
HID: add ALWAYS_POLL quirk for a Logitech 0xc007
HID: wacom: rely on actual touch down count to decide touch_down
HID: wacom: do not send pen events before touch is up/forced out
