I've noticed your "ASoC: soc-core: don't use soc_find_component() at
snd_soc_find_dai()" patch, but sadly it doesn't fix any issue with the
Samsung I2S and Snow ASoC driver. Do you want me to send revert to all
the needed commits to restore audio on Samsung Chromebooks: Snow, Pit
and Pi, Odroid XU and Samsung TM2 boards?
Best regards
