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.
