-Subject: [PATCH] staging: vc04_services: Split vchiq-mmal into a
- module
-
-In preparation for adding a video codec V4L2 module which also
-wants to use vchiq-mmal functions, split it out into an
-independent module.
-The minimum number of changes have been made to achieve this
-(eg straight moves where possible) so existing checkpatch
-errors will still be present.

-Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>
