[alsa-devel] [PATCH 031/187] ASoC: wm8978: replace codec to component

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com

Now we can replace Codec to Component. Let's do it.

Note: xxx_codec_xxx() -> xxx_component_xxx() .idle_bias_off = 0 -> .idle_bias_on = 1 .ignore_pmdown_time = 0 -> .pmdown_time = 1 - -> .endianness = 1 - -> .non_legacy_dai_naming = 1
