[alsa-devel] [PATCH v4 4/9] ASoC: simple-card-utils: enable "label" on asoc_simple_card_parse_card_name

[Kuninori Morimoto]

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

Current asoc_simple_card_parse_card_name() detect [prefix]name,
but in generally, we uses "label" for user visible names.
This patch expand it to [prefix]label.
This patch also update simple-xx-card.txt which is using this feature
