From: Kuninori Morimoto Date: Tue, 31 May 2016 08:59:46 +0000 (+0000) Subject: ASoC: simple-card: add new asoc_simple_jack and use it X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9eac361877b3c96c8f68dffd7a7a3e92a2b85d0b;p=linux-beck.git ASoC: simple-card: add new asoc_simple_jack and use it Current simple-card supports snd_soc_jack/pin/gpio. These code are very similar, but driver has verbosity code. So, this patch adds new snd_soc_jack and cleanups code Signed-off-by: Kuninori Morimoto Signed-off-by: Mark Brown --- diff --git a/sound/soc/generic/simple-card.c b/sound/soc/generic/simple-card.c index b6e6d9a12ec2..8d0311ceded1 100644 --- a/sound/soc/generic/simple-card.c +++ b/sound/soc/generic/simple-card.c @@ -21,6 +21,12 @@ #include #include +struct asoc_simple_jack { + struct snd_soc_jack jack;
