Because, snd_soc_find_dai() is called both with/without client_mutex. (same/sof are calling it with mutex, simple-card/audio-graph are calling without mutex) Other solution is create both snd_soc_find_dai_with_mutex()/without_mutex(). I'm not sure which style is best. Thank you for your help !! Best regards --- Kuninori Morimoto
