Subject: [PATCH] Revert "ALSA: hda: Drop workaround for a hang at shutdown again"
Git-commit: 6f44578430d7888ade1e3bd919c1c2c0724409e5
Patch-mainline: v5.15-rc4
References: bsc#1192354
This reverts commit 8fc8e903156f42c66245838441d03607e9067381.
It was expected that the fixes in HD-audio codec side would make the
workaround redundant, but unfortunately it doesn't seem sufficing.
Resurrect the workaround for now.
