+Subject: [PATCH] ALSA: hda/via: Fix runtime PM for Clevo W35xSS
+
+Clevo W35xSS_370SS with VIA codec has had the runtime PM problem that
+looses the power state of some nodes after the runtime resume.  This
+was worked around by disabling the default runtime PM via a denylist
+entry.  Since 5.10.x made the runtime PM applied (casually) even
+though it's disabled in the denylist, this problem was revisited.  The
+result was that disabling power_save_node feature suffices for the
+runtime PM problem.
+
+This patch implements the disablement of power_save_node feature in
+VIA codec for the device.  It also drops the former denylist entry,
+too, as the runtime PM should work in the codec side properly now.
+
+Fixes: b529ef2464ad ("ALSA: hda: Add Clevo W35xSS_370SS to the power_save blacklist")
