Public bug reported:
[Impact]
After system S3, hotplugging headset cannot produce any sound despite of
being auto-selected as audio output.
[Fix]
Avoid using pm_runtime_force_{suspend,resume} helpers to ensure codec
suspend/resume flow, and also ensure HDA driver and PCI set correct
wakeup settings.
[Test case]
Plug headset, unplug headset, switch audio ouput from speakers to HDMI
to let Intel HDA auto suspend. Suspend/resume the system, plug the
headset again, hear no sound.
With the patch series applied, the issue is gone.
[Where problems could occur]
If there is bad firmware/hardware that makes codec have system-wide
wakeup capability, direct-complete flow may trigger unwanted system
wakeup or even break system suspend. The series was tested on both AMD
and Intel platforms, with Realtek and Connexant codecs respectively.
