Browse Source 
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
