From 0e3460bceedc98176684602a34659d51cd8bd4ce Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Fri, 30 Nov 2018 02:07:48 +0000 Subject: [PATCH] ASoC: audio-graph-card: use cpu/codec pointer on graph_dai_props In DPCM case, it uses CPU-dummy / dummy-Codec dai links, and non DPCM case, it uses CPU-Codec dai links. Now, we want to merge audio-graph-card and audio-graph-scu-card. These sound cards are using silimar but not same logic on each functions. Then, of course we want to share same logic. To compromise, this patch uses cpu/codec pointer on audio-graph-card. It is same logic with audio-graph-scu-card, thus easy merging. This is prepare for merging audio card Signed-off-by: Kuninori Morimoto Signed-off-by: Mark Brown --- sound/soc/generic/audio-graph-card.c | 57 +++++++++++++++++----------- 1 file changed, 34 insertions(+), 23 deletions(-) diff --git a/sound/soc/generic/audio-graph-card.c b/sound/soc/generic/audio-graph-card.c index 1b158cc2df88..1da9532ef897 100644 --- a/sound/soc/generic/audio-graph-card.c +++ b/sound/soc/generic/audio-graph-card.c @@ -23,8 +23,8 @@ struct graph_card_data { struct snd_soc_card snd_card;
