Subject: [PATCH 04/23] ASoC: soc-core: adjust for graph on snd_soc_of_parse_card_name
From: Kuninori Morimoto <kuninori.morimoto.gx@...esas.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
