[Bug 1490895] Re: Skylake/Broadwell/Haswell: No HDMI audio jack detection in D3
I'm not sure it's regression issue or not, but it's also happen on 3.19
kernel ( 3.19.0-27 ) "with" HDMI plug, if I unplug the HDMI and test it
again then the system can be shutdown without hang.
so the different between original kernel and bpo 2.2 is : bpo 2.2 encounter shutdown hang "without" HDMI plug
and both encounter this issue "with" HDMI plug.

Skylake/Broadwell/Haswell: No HDMI audio jack detection in D3

When the HDA audio controller is in D3, a hotplug event (i e, HDMI or
DisplayPort being plugged in) fails to wake up the audio side so it
never registers that something has happened.
By having the i915 driver call directly into the hda driver, the HDA
driver is always notified that an HDMI hotplug event has happened.
