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

Pull HID fixes from Jiri Kosina:

 - a partial revert of exponent parsing changes to make "Unit" exponent
   item work properly again, by Nikolai Kondrashov

 - a few new device IDs additions piggy-backing, by AceLan Kao and David
   Herrmann

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid:
  HID: wiimote: add LEGO-wiimote VID
  HID: Fix unit exponent parsing again
  HID: usbhid: quirk for SiS Touchscreen
  HID: usbhid: quirk for Synaptics Large Touchccreen
