But after that it will check cpu_dai->name and dai_link->cpu_dai_name too. On the other hand, snd_soc_dai :: name is created by fmt_single_name() or fmt_multiple_name(). There is no confusion if dai name is created by fmt_multiple_name(), since cpu_dai->name is same as dai_link->cpu_dai_name. but, if dai name is created by fmt_single_name(), CPU DAI never match. Thus, simple-card not set dai_link->cpu_dai_name if DT case to skip naming match on soc_bind_dai_link() Signed-off-by: Kuninori Morimoto Signed-off-by: Mark Brown (cherry picked from commit f687d900d30a61dda38db2a99239f5284a86a309) Signed-off-by: Simon Horman --- sound/soc/generic/simple-card.c | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/sound/soc/generic/simple-card.c b/sound/soc/generic/simple-card.c index bdd176d..034a2b7 100644 --- a/sound/soc/generic/simple-card.c +++ b/sound/soc/generic/simple-card.c @@ -234,6 +234,17 @@ static int asoc_simple_card_parse_of(struct device_node *node, priv->codec_dai.fmt, priv->codec_dai.sysclk); + /* + * soc_bind_dai_link() will check cpu name + * after of_node matching if dai_link has cpu_dai_name. + * but, it will never match if name was created by fmt_single_name() + * remove cpu_dai_name to escape name matching. + * see + * fmt_single_name() + * fmt_multiple_name() + */ + dai_link->cpu_dai_name = NULL; + return 0; }
