Hi Marek sorry for bother you > 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? It and your issue are both from my miss-understanding (= some CPU is using generic DMAEngine), but needs different patch. I'm now negotiating to Mark about it, and I will post revert/fixup patch, soon. Again, I'm so sorry to bother you. Thank you for your help !! Best regards --- Kuninori Morimoto
