[PATCH 6/7] [media] ati_remote: add support for SnapStream Firefly remote

From: Anssi Hannula
Date: Sat Aug 06 2011 - 18:28:32 EST


Add support for SnapStream Firefly remote control.

The protocol differs by having two toggle bits in the scancode. Since
one of the bits is otherwise unused, we can safely handle the bits
unconditionally.
