Thanks a lot for your feedback - it is reassuring that it looks sane to you.

Next steps will be to address your comments, re-test, submit a new series,
add to -next after v4.8-rc1 is out, submit the conversions I have done
and add to -next. Then, obviously, only accept new drivers using the
new API.

Not sure if there is anything else we can or want to do do at this time.
Do you have anything in mind ?
