[alsa-devel] [PATCH 7/7] ASoC: soc-core: remove null_snd_soc_ops

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

All rtd->dai_link callback functions are controlled by soc_rtd_xxxx(),
and checking rtd->dai_link->ops.
We don't need to have null_snd_soc_ops anymore.
This patch removes it.
