So why is this needed?!? This error came from "simple-audio-card", not "rcar_sound" I think. # sound needs many drivers... Actually, I don't want to have default #sound-dai-cells in r8a7778.dtsi. Like below. I will send this patch soon ad63241cdc328edbb0f879416ea7707bf0997f08 ("ARM: shmobile: r8a7790: tidyup #sound-dai-cells settings")
