Meanwhile, the actual culprit of the hang was identified to be the leftover active codecs that may interfere with the powered down controller somehow, but we took a minimal fix approach for 5.14, and that was the commit above. Now, since the codec drivers go runtime-suspend at shutdown for 5.15, we can revert the change and make sure that the full runtime-suspend is performed at shutdown of HD-audio controller again. This patch essentially reverts the commit above to restore the behavior.
