Re: [PATCH] CHROMIUM:ASOC: amd: Add Machine driver Support for rt5682s codec

is the CHROMIUM prefix intentional? this should be ASoC: amd: ...

reverse x-mas tree style?

not really useful?

test the clocks?

also use devm_ ...

... since in this case and below the clocks are not released.

and actually the clock and jack should be handled in the platform driver probe, not here. This wouldn't work if you remove the platform driver, would it?

how does '9835' relate to RT5682s? You may want at least a comment.
