-Subject: [PATCH] staging: mmal-vchiq: Make a mmal_buf struct for
- passing parameters
-
-The callback from vchi_mmal to the client was growing lots of extra
-parameters. Consolidate them into a single struct instead of
-growing the list further.
-The struct is associated with the client buffer, therefore there
-are various changes to setup various containers for the struct,
-and pass the appropriate members.
