From c590fa80b39287a91abeb487829f3190e7ae775f Mon Sep 17 00:00:00 2001 From: Shengjiu Wang Date: Fri, 3 Sep 2021 18:30:06 +0800 Subject: [PATCH] ASoC: fsl_xcvr: register platform component before registering cpu dai There is no defer probe when adding platform component to snd_soc_pcm_runtime(rtd), the code is in snd_soc_add_pcm_runtime() snd_soc_register_card() -> snd_soc_bind_card() -> snd_soc_add_pcm_runtime() -> adding cpu dai -> adding codec dai -> adding platform component. So if the platform component is not ready at that time, then the sound card still registered successfully, but platform component is empty, the sound card can't be used. As there is defer probe checking for cpu dai component, then register platform component before cpu dai to avoid such issue.
