[alsa-devel] [PATCH v5 5/9] ASoC: soc-core: enable "dai-name" on snd_soc_of_parse_daifmt()

[Kuninori Morimoto]

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

Current snd_soc_of_parse_daifmt() detects [prefix]format, but
"format" was unclear in some case. This patch enables
[prefix]dai-format, too.
