Public bug reported:
This is a long-standing bug for some Haswell, Broadwell and most Skylake
machines.
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.
