Hi and thanks for working on this.

I've been trying to reproduce the above, but I can't seem to activate
runtime PM at all. I can't seem to get a callback to runtime_suspend,
and further investigation shows that
/sys/class/sound/card0/power/runtime_status shows "unsupported".

And this is on 3.13-rc1, and there *shouldn't* be any Ubuntu specific
stuff or configuration in that kernel.

Any ideas? (Sorry if this is a newbie question..)
