Sorry, but how about people try to come up with _a solution_ first.
There's been loads of talk about this, lots of drivers trying to do
integrated or driver specific approaches, but only one or two attempts
at doing something driver independent.

If all the effort that's been put into discussion was put into sorting
out a solution, maybe we'd be a little further forward than we are now.

I've sent one proposal which uses a notifier to inform audio and CEC
drivers about state changes in the HDMI video side, and had precisely
zero replies to it - people seemed to prefer discussing stuff rather
than reviewing code and coming up with actual solutions.
