From 38e42f6d6c6702bbfc633fce9b579fb80cec2d59 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Thu, 6 Apr 2023 00:16:10 +0000 Subject: ASoC: expand snd_soc_dpcm_mutex_lock/unlock() soc-pcm.c has snd_soc_dpcm_mutex_lock/unlock(), but other files can't use it because it is static function. It requests snd_soc_pcm_runtime as parameter (A), but sometimes we want to use it by snd_soc_card (B). (A) static inline void snd_soc_dpcm_mutex_lock(struct snd_soc_pcm_runtime *rtd) { mutex_lock_nested(&rtd->card->pcm_mutex, rtd->card->pcm_subclass); } ^^^^^^^^^ (B) mutex_lock_nested(&card->pcm_mutex, card->pcm_subclass); ^^^^ We want to use it with both "rtd" and "card" for dapm lock/unlock. To enable it, this patch uses _Generic macro. This patch makes snd_soc_dpcm_mutex_{un}lock() global function, and use it on each files.
