I think it's not a big risk if Angelo already did the test and
snd_soc_pm_ops is also used in MT8186.
I can help do more tests on 5.10 when the patch is back to chromium in
the future.
MTK also have a plan to support complete suspend/resume functionality
in MT8195. If Tzung-bi has concerns about the patch, I can help submit
the patch at the time.

Thanks,
