I don't do suspend on this laptop, I poweroff and reboot when I get
wherever I'm going.

However... device-level power management? Hmm.. I *do* remember that
each time I found it dead, I was coming back to my laptop from doing something
else, so the sound would have been idle....

ALSA: hda - Fix possible runtime PM refcount unbalance

That landed in next-20150324 - which is broken for me.

Looks worth trying a revert before I bisect, thanks for the hint, will
report back (probably tomorrow) on what happens...
