[alsa-devel] [PATCH 10/15] ASoC: simple-card-utils: share asoc_simple_dai_init()

[Kuninori Morimoto]

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

The difference between simple-card / audio-graph are just using
OF graph style, or not. In other words, other things should be same.
This means, simple-card/audio-graph common functions should be
implemented at simple-card-utils, and its own functions should be
implemented at each files.

Current simple-card / audio-graph have almost same functions.
This patch shares asoc_simple_dai_init() between in these 2 drivers.
