Sounds good.  I was looking at re-using some of the config options
(HDMI codec and power save) for the platform driver as well.  Maybe
something like the following.  SND_HDA would build the helper module
and hda-codec that are used by both hda_intel and a platform driver.

I can add that to the end of the series or it can move it whenever is
convenient, not sure how many pending patch sets it would disrupt.

Thanks!
