From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com
audio-graph-card is now supporting normal sound and DPCM ound. For DPCM sound, original sound card (= audio-graph-scu) had been supported 1 CPU : 1 Codec connection which uses hw_params_fixup() for convert-rate/channel. But, merged audio-graph-card is completely forgeting about it.
This patch re-support it.
