Subject: [BUG] [REGRESSION] [BISECTED] -rc1 breaks audio over HDMI for i915

The following change:

788d441 ALSA: hda - Use component ops for i915 HDMI/DP audio jack handling

breaks audio over HDMI on my snd_hda_intel laptop. It is the first bad
commit.

This was merged for -rc1 and isn't fixed until now, so I got nervous.
There are
no errors in the log that stand out. I'm no sound or alsa developer, and
just reverting it isn't easy since there is stuff depending on this.

I'm happy to test possible fixes and hope v4.5 not to ship with such a big
regression ;)
