From 9c712e4f57229081e837d593fc1e4183b068a41c Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Fri, 26 Jul 2019 13:52:00 +0900 Subject: ASoC: soc-component: add snd_soc_pcm_component_page() Current ALSA SoC is directly using component->driver->ops->xxx, thus, the code nested deeply, and it makes code difficult to read, and is not good for encapsulation. We want to implement component related function at soc-component.c, but, some of them need to care whole snd_soc_pcm_runtime (= rtd) connected component. Let's call component related function which need to care with for_each_rtdcom() loop as snd_soc_pcm_component_xxx(). This patch adds new snd_soc_pcm_component_page() and use it.
