This needs the same fix for the subject prefix that I mentioned for your
other patch, otherwise:

Reviewed-by: Thierry Reding <treding@...dia.com>

Perhaps a good idea would be to send all of these patches with the

That makes it easier for people to pick them up (assuming Dave will take
them directly).
