[alsa-devel] [PATCH 166/187] ASoC: cx20442: replace codec to component

Fri Jan 12 02:55:40 CET 2018


From: Kuninori Morimoto <kuninori.morimoto.gx at 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
