This should never have gone into my tree if there wasn't someone in the 
v4l tree who knew it was coming,

In future please merge the media-bus-formats through both tree, providing
a stable git tree to both maintainers to pull from, though this may not
avoid all bad cases, it hopefully will avoid this sort of mess.

I'm not really sure how best to clean this one up, I think I'd want
patches to my tree that just use the correect values, then it would just 
be a normal conflict on merging, instead of renumbering userspace visible
values,

Dave.
