[alsa-devel] [PATCH 06/14] ASoC: soc-core: move snd_soc_find_dai_link()

[Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>]

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

snd_soc_find_dai_link() is soc-topology specific function.
We don't need to have it at soc-core.
This patch moves it to soc-topology.c
