From: Kuninori Morimoto kuninori.morimoto.gx@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 are initializing each priv, but it is same operation. This patch adds new asoc_simple_card_init_priv() and initialize priv by same operation.
