[alsa-devel] [PATCH 03/39 v2] ASoC: simple-card: add new asoc_simple_jack and use it

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>
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
