[PATCH v7 6/9] ASoC: simple-card-utils: enable "label" on asoc_simple_card_parse_card_name

[Kuninori Morimoto <kuninori.morimoto.gx-zM6kxYcvzFBBDgjK7y7TUQ@public.gmane.org>]

From: Kuninori Morimoto <kuninori.morimoto.gx-zM6kxYcvzFBBDgjK7y7TUQ@public.gmane.org>

Current asoc_simple_card_parse_card_name() detects [prefix]name,
but in generally, we uses "label" for user visible names.
This patch enables it.
