From 5d9fa03e6c3514266fa94851ab1b6dd6e0595a13 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 10 Feb 2020 12:14:45 +0900 Subject: [PATCH] ASoC: soc-pcm: tidyup soc_pcm_open() order soc_pcm_open() operation order is not good. At first, soc_pcm_open() operation order is 1) CPU DAI startup 2) Component open 3) Codec DAI startup 4) rtd startup But here, 2) will call try_module_get() if component has module_get_upon_open flags. This means 1) CPU DAI startup will be operated *before* its module was loaded. DAI should be called *after* Component. Second, soc_pcm_close() operation order is 1) CPU DAI shutdown 2) Codec DAI shutdown 3) rtd shutdown 4) Component close soc_pcm_open() and soc_pcm_close() are paired function, but, its operation order is unbalance. This patch tidyup soc_pcm_open() order to Component -> rtd -> DAI.
