This looks very broken, you're setting the two ends of the link to different configurations.  If this is needed it should be documented why.

Also, this should be set in the dai_link structure as data rather than set each time.

OK. codec is slave, i2s controller is master. So, I'll use SND_SOC_DAIFMT_CBS_CFM.

thanks.
