Media change look ok, and probably the other patches too, but the
problem here is: who will apply it and when.

The way you grouped the changes makes harder for subsystem maintainers
to pick, as the same patch touches multiple subsystems.

On the other hand, if this gets picked by someone else, it has the
potential to cause conflicts between linux-next and the maintainer's
tree.

So, the best would be if you re-arrange this series to submit one
patch per subsystem.
