ASoC: audio-graph-card: tidyup prefix for snd_soc_codec_conf
Current audio-graph-card is handling "prefix" by many ways. But, it is not useful and readable. We want to do is that allow having it everywere. This patch supports it. It will be overwrote if lower node has it. sound { prefix = "xxx"; // initial }; codec { audio-graph-card,prefix = "xxx"; // overwrite ports { prefix = "xxx"; // overwrite port { prefix = "xxx"; // overwrite }; }; }; Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
