Yes we wanted to decouple the sdw and audio bits that is the reason why none of the audio types are used here, but I think it should be revisited and perhaps made as: sdw_config_stream(struct device *sdw, struct sdw_callback_ctx *ctx) where the callback context contains all the other args. That would make it look lot neater too and of course use real structs if possible -- ~Vinod _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
