[alsa-devel] [PATCH 3/4] ASoC: soc-core: soc_find_component() uses snd_soc_dai_link_component

[Kuninori Morimoto]

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

soc_find_component() is using "of_node" and "name" to finding component,
but we should use snd_soc_dai_link_component now, because it is created
to such purpose.

This patch uses snd_soc_dai_link_component for soc_find_component().
