soc.h has snd_soc_dapm_mutex_lock/unlock() definition and
many drivers are using it, but soc-dapm.c is not.
1st reason is snd_soc_dapm_mutex_lock/unlock() requests
snd_soc_dapm_context pointer as parameter (A), but sometimes soc-dapm.c
needs to use snd_soc_card (B).
(A) static inline void snd_soc_dapm_mutex_lock(struct snd_soc_dapm_context *dapm)
{
mutex_lock_nested(&dapm->card->dapm_mutex, SND_SOC_DAPM_CLASS_RUNTIME);
} ^^^^^^^^^^
(B) mutex_lock_nested(&card->dapm_mutex, SND_SOC_DAPM_CLASS_RUNTIME);
^^^^
2nd reason is it want to use SND_SOC_DAPM_CLASS_INIT for mutex_lock_nested(),
but helper is using _RUNTIME (A).
The conclusion is we want to use "dapm vs card" and "_RUNTIME vs _INIT"
for dapm lock/unlock. To enable this selfish request, this patch uses
_Generic macro. We can use snd_soc_dapm_mutex_lock/unlock() for both
dapm and card case.
snd_soc_dapm_mutex_lock(dapm); snd_soc_dapm_mutex_unlock(dapm);
snd_soc_dapm_mutex_lock(card); snd_soc_dapm_mutex_unlock(card);
Current soc-dapm.c is using both mutex_lock() and mutex_lock_nested().
This patch handles mutex_lock() as mutex_lock_nested(..., 0),
in other words, handles below as same.
mutex_lock(&card->dapm_mutex);
mutex_lock_nested(&card->dapm_mutex, SND_SOC_DAPM_CLASS_INIT);
Because people might misunderstand that _init() is mutex initialization,
this patch renames _INIT to _ROOT and adds new
snd_soc_dapm_mutex_lock_root() for it.
This patch also moves snd_soc_dapm_subclass definition from soc-dapm.h
to soc.h to keep related code together.
Because very complex soc.h vs soc-dapm.h relationship,
it is difficult/impossible to define these helper into soc-dapm.h.
