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") Reported-by: Christian Labisch <clnetbox@gmail.com> Cc: <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20210104153046.19993-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
