ASoC: audio-graph-scu-card: tidyup asoc_simple_card_parse_daifmt() timing
Current audio-graph-scu-card driver is parsing codec position for DPCM and consider DAI format. But, current operation is doing totally pointless, because 1) asoc_simple_card_parse_daifmt() will be called not only for 1st codec on current implementation, and it will be used as fixed format 2) it should be called for each CPU/Codec pair. Let's tidyup asoc_simple_card_parse_daifmt() timing. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
