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

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid:
  HID: length resolution should be reported units/mm
  HID: add support for F430 Force Feedback Wheel
  HID: egalax: Use kzalloc
  HID: Remove KERN_DEBUG from dbg_hid use

Manually fixed trivial conflict in drivers/hid/hid-input.c (due to
removal of KERN_DEBUG from dbg_hid use clashing with new keycode
interface switch)
