[alsa-devel] [PATCH v3 02/17] ASoC: soc-core: adjust for graph on snd_soc_of_parse_audio_simple_widgets

[Kuninori Morimoto]

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

It is assuming that the card related information is located on
"card" node, but graph case doesn't have it.
This patch adds node parameter to adjust for graph support
