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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
