[alsa-devel] [PATCH 022/187] ASoC: wm8741: replace codec to component

12 Jan 2018

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
