I realised while (re)creating the test branches (sent in reply to the cover
letter), I missed to squash this hunk in
"staging: vc04_services: bcm2835-isp: Add a more complex ISP processing component"
before sending out the series.

Sending it as a fixup! for now.
sorry, but i lost track of all your vchiq patch series. Usually a
commiter shouldn't send multiple series to a list at the same time. This
is very hard to review / test.

An expected review time for a patch series should be 2 weeks, especially
such big series like bcm2835-isp.

For this specific case, it would be better to reply to your own patch
and mention this mistake and fix. It's clear that we need a V3 of the
bcm2835-isp, so in this series the fix should be finally included.

I didn't had the time for the big series, but sending more patches
doesn't make me faster ...

Regards
Stefan
