From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> I was wondering why my VLV no longer runtime suspended, and after some thinking I decided it had to be the LPE audio preventing it. Turns out I was right, so here's my attempt at fixing it. And while looking at the code I couldn't help but notice that it couldn't actually handle multiple pipes playing back audio at the same time. And even having multiple displays active even if only one was playing audio was probably a recipe for failure. So I tried to fix that by registering a separate PCM device for each pipe. Note that the patch subjects may not reflect the subsystem very well since most of these straddle the border between drm and alsa. I think I just slapped on drm/i915 to most where there was no clear winner.
