[alsa-devel] [RFC][PATCH 1/x] ASoC: snd_soc_component_driver has snd_pcm_ops

Kuninori Morimoto kuninori.morimoto.gx at renesas.com
Tue Jun 20 04:26:40 CEST 2017


snd_soc_platform_driver has snd_pcm_ops,
and it will be replaced into snd_soc_component_driver in the future.
To prepare it, component driver has it.
