Sorry for taking so long. This got burried under a lot of other stuff. I
have some minor comments to patch 2/3, but on the whole this looks very
nice.

I'm not aware of anyone currently doing work on this for DRM, so I think
it'd be fine if you took it through the media git tree, especially since
patch 3/3 clearly belongs there.

If we ever need to resolve dependencies between this and new work in DRM
we could set up a stable branch containing patches 1/3 and 2/3 which can
be merged into both trees.
