Apologies for the way too long delay. I felt it would have been unfair
to ask you to do the changes I thought were necessary after such a
delay, so I sent them as patches... The last one still needs review, but
at least the mundane stuff is out of the way now.

Ville is on vacation, not sure whom else would be a good reviewer from our
side ... Might need to escalate to managers to finding a random reviewer
who first needs to ramp up on hdmi/audio issues.
