Thank you - sounds like progress.

Is this series also already sufficient to consider the TODO at
drivers/staging/vc04_services/interface/TODO as addressed? if so - a
patch at the end of the series which removes the todo items would be
good to include in the series (and other cleanup series) so that the
TODO list gets updated as we progress.
