Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid 

Pull HID fixes from Jiri Kosina:

 - fix for how scaling linearization is computed in wiimote driver, by
   Cyan Ogilvie

 - endless retry loop fix in generic USB HID core reset-resume handling,
   by Alan Stern

 - two functional fixes affecting particular devices, and oops fix for
   wacom driver, by Jason Gerecke

 - multitouch slot numbering fix from Gabriele Mazzotta

 - a couple more small fixes on top

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid:
  HID: wacom: Support switching from vendor-defined device mode on G9 and G11
  HID: wacom: Initialize hid_data.inputmode to -1
  HID: microsoft: add support for 3 more devices
  HID: multitouch: Synchronize MT frame on reset_resume
  HID: wacom: fix Bamboo ONE oops
  HID: lenovo: Don't use stack variables for DMA buffers
  HID: usbhid: fix inconsistent reset/resume/reset-resume behavior
  HID: wiimote: Fix wiimote mp scale linearization
