Subject: [PATCH] ASoC: hdac_hda: allow runtime pm at end of probe
Git-commit: 7a2ba46f3693ec8fbd508c4e693692e85ac14ed6
Patch-mainline: v5.10-rc1
References: git-fixes
Align with recent change to forbid runtime suspend during codec
init in snd_hda_codec_device_new(), with matching call to
allow suspend at end of hdac_hda_codec_probe().
In snd-hda-intel, call to snd_hda_set_power_save() at end of
controller probe does the same thing, but ASoC controller drivers
do not modify runtime settings for codecs, so this has to be done
in codec drivers, and in this case in hdac_hda.
