4 Subject: [PATCH] staging: vc04_services: Split vchiq-mmal into a
5 module
6
7 In preparation for adding a video codec V4L2 module which also
8 wants to use vchiq-mmal functions, split it out into an
9 independent module.
10 The minimum number of changes have been made to achieve this
11 (eg straight moves where possible) so existing checkpatch
12 errors will still be present.
