ASoC: expand snd_soc_dapm_mutex_lock/unlock()
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.

ASoC: soc-dapm.c: tidyup dapm_connect_dai_pair()
dapm_connect_dai_pair() handles
"Normal/Codec2Codec" x "CPU/Codec" x "Playback/Capture".

(A) is "Codec2Codec" case of "CPU"   widget x "Playback/Capture",
(B) is "Normal"      case of "CPU"   widget x "Playback/Capture",
(C) is each          case of "Codec" widget.

(X) is handling "Playback" case DAI connecting,
(Y) is handling "Capture"  case DAI connecting.

	static void dapm_connect_dai_pair(...)
	{
		...

(A)		if (dai_link->params) {
			playback_cpu	= ...
			capture_cpu	= ...
(B)		} else {
			playback_cpu	= ...
			capture_cpu	= ...
		}

 ^		/* connect BE DAI playback if widgets are valid */
 |		stream = SNDRV_PCM_STREAM_PLAYBACK;
 | (C)		codec = codec_dai->playback_widget;
 |
 |		if (playback_cpu && codec) {
(X)			if (dai_link->params && !rtd->c2c_widget[stream]) {
 |				...
 |			}
 |
 | (z)			dapm_connect_dai_routes(...);
 v		}

	capture:
 ^		/* connect BE DAI capture if widgets are valid */
 |		stream = SNDRV_PCM_STREAM_CAPTURE;
 | (C)		codec = codec_dai->capture_widget;
 |
 |		if (codec && capture_cpu) {
(Y)			if (dai_link->params && !rtd->c2c_widget[stream]) {
 |				...
 |			}
 |
 | (z)			dapm_connect_dai_routes(...);
 v		}
	}

(X) part and (Y) part are almost same.
Main purpose of these parts (and this function) is calling
dapm_connect_dai_routes() (= z) on each cases.
The difference is "parameter"
(= Normal/Codec2Codec x CPU/Codec x Playback/Capture).

This patch cleanup these, but nothing changed for meaning.

ASoC: dapm: Sort speakers after other outputs
Currently we sequence speakers with line and headphone outputs in DAPM.
This works well when speakers are integrate into a CODEC but when there is
an external speaker driver connected to a line or headphone output it can
mean that the speaker driver ends up getting sequenced such that it picks
up pops and clicks from the CODEC. Mask this by moving speakers after the
other outputs in DAPM.

We may want to consider doing this for headphones too but separate drivers
are less common there and headphone drivers often also function as line
outputs so the situation is less clear.

snd_soc_dapm_new_dai() setups local variable "template" at (X) and (Y),

ASoC: soc-dapm.c: tidyup error handling on snd_soc_dapm_add_route()
Current error handling on snd_soc_dapm_add_route() has some wastes.
It indicates *own* error message *only* for sink or source,
and return error directly at (A). OTOH, it has similar error message at
(B) which indicates *both* sink/source.

And more, (A) is using dev_err(), (B) is using dev_warn().
(B) is caring prefix, but (A) is not.

(X)	int snd_soc_dapm_add_route(...)
	{
		...
		if (wsource == NULL) {
(A)			dev_err(...);
			return -ENODEV;
		}
		if (wsink == NULL) {
(A)			dev_err(...);
			return -ENODEV;
		}

		...

		ret = snd_soc_dapm_add_path(...);
		if (ret)
(B)			goto err;

		return 0;
	err:
(B)		dev_warn(...);
		return ret;
	}

Above snd_soc_dapm_add_route() (= X) is called from
snd_soc_dapm_add_routes() (= Y).
(X) will indicate error message by itself, but (Y) will indicate
own error message at (C). (C) is duplicated.

(Y)	int snd_soc_dapm_add_routes(...)
	{
		...
		for (...) {
(X)			int r = snd_soc_dapm_add_route(...);
			if (r < 0) {
(C)				dev_err(...);
				ret = r;
			}
			...
		}
		...
	}

This patch (1) merges these error message (= A,B) into one,
(2) use dev_err(), (3) remove duplicate error message (= C) from
snd_soc_dapm_add_routes().

By this patch, it will indicate error message like this.

	- error message with prefix
	- not found widget will have "(*)" mark
	- it indicates [control] if exists.

ex)
[if no sink with control]

	ASoC: Failed to add route SOURCE -> [CTRL] -> SINK(*)

[if no source without control]

ASoC: soc-dapm.c: tidyup snd_soc_dai_link_event_pre_pmu()
snd_soc_dai_link_event_pre_pmu() is using if/else for config->formats
check, but "else" case is for just error.
Unnecessary if/else is not good for readable code. this patch checks
if config->formats was zero as error case.

Moreover, we don't need to indicate config->formats value in error message,
because it is zero. This patch tidyup it, too.

=>	if (config->formats) {
		...
	} else {
		dev_warn(w->dapm->dev, "ASoC: Invalid format %llx specified\n",
=>			 config->formats);
		...
	}

ASoC: soc-dapm.c: add comment for kzalloc()/kfree() on snd_soc_dai_link_event_pre_pmu()
snd_soc_dai_link_event_pre_pmu() is using kzalloc()/kfree() for params.
It looks we don't need to use these, but are necessary.
But, it is difficult to know why it is necessary without any comments.
This patch adds the reasons via comment.

ASoC: soc-dapm.c: fixup snd_soc_dapm_new_control_unlocked() error handling
Current snd_soc_dapm_new_control_unlocked() error handling is wrong.
It is using "goto request_failed" (A), but error message is using
"w->name" (B) which is not yet created in such timing.

	snd_soc_dapm_new_control_unlocked(xxx)
	{
		...
		switch (w->id) {
		case xxx:
			...
			if (IS_ERR(...)) {
				ret = PTR_ERR(...);
(A)				goto request_failed;
			}
		...
		}

		prefix = soc_dapm_prefix(...);
		if (prefix)
(B)			w->name = kasprintf(...);
		else
(B)			w->name = kstrdup_const(...);
		...

(A)	request_failed:
		if (ret != -EPROBE_DEFER)
(B)			dev_err(..., w->name, ...);

		return ...;
	}

we can create "w->name" at beginning of this function.
In such case, we need to call kfree_const(w->name) at error case.
This patch do these.

ASoC: dapm: Initialise kcontrol data for mux/demux controls
DAPM keeps a copy of the current value of mux/demux controls,
however this value is only initialised in the case of autodisable
controls. This leads to false notification events when first
modifying a DAPM kcontrol that has a non-zero default.

Autodisable controls are left as they are, since they already
initialise the value, and there would be more work required to
support autodisable muxes where the first option isn't disabled
and/or that isn't the default.

Technically this issue could affect mixer/switch elements as well,
although not on any of the devices I am currently running. There
is also a little more work to do to address the issue there due to
that side supporting stereo controls, so that has not been tackled
in this patch.

ASoC: dapm: Don't fold register value changes into notifications
DAPM tracks and reports the value presented to the user from DAPM controls
separately to the register value, these may diverge during initialisation
or when an autodisable control is in use.

When writing DAPM controls we currently report that a change has occurred
if either the DAPM value or the value stored in the register has changed,
meaning that if the two are out of sync we may appear to report a spurious
event to userspace. Since we use this folded in value for nothing other
than the value reported to userspace simply drop the folding in of the
register change.

ASoC: soc-dapm: fix two incorrect uses of list iterator
These two bug are here:
	list_for_each_entry_safe_continue(w, n, list,
					power_list);
	list_for_each_entry_safe_continue(w, n, list,
					power_list);

After the list_for_each_entry_safe_continue() exits, the list iterator
will always be a bogus pointer which point to an invalid struct objdect
containing HEAD member. The funciton poniter 'w->event' will be a
invalid value which can lead to a control-flow hijack if the 'w' can be
controlled.

The original intention was to continue the outer list_for_each_entry_safe()
loop with the same entry if w->event is NULL, but misunderstanding the
meaning of list_for_each_entry_safe_continue().

So just add a 'continue;' to fix the bug.

ASoC: Export DAI register and widget ctor and dctor functions
To allow for more flexibility i.e. populating component DAIs dynamically
during its initialization, without being limited to topology loading
procedure, expose snd_soc_register(), snd_soc_dapm_new_dai_widgets() and
snd_soc_dapm_free_widget() functions.

Allows users to first check available resources e.g. number of PCMs
supported by HDAudio codec before allocating the number of DAPM
widgets needed. This prevents superfluous objects from being created or
allows driver to adjust to situation when resources are limited.

ASoC: DAPM: Cover regression by kctl change notification fix
The recent fix for DAPM to correct the kctl change notification by the
commit 5af82c81b2 ("ASoC: DAPM: Fix missing kctl change
notifications") caused other regressions since it changed the behavior
of snd_soc_dapm_set_pin() that is called from several API functions.
Formerly it returned always 0 for success, but now it returns 0 or 1.

This patch addresses it, restoring the old behavior of
snd_soc_dapm_set_pin() while keeping the fix in
snd_soc_dapm_put_pin_switch().

ASoC: DAPM: Fix missing kctl change notifications
The put callback of a kcontrol is supposed to return 1 when the value
is changed, and this will be notified to user-space.  However, some
DAPM kcontrols always return 0 (except for errors), hence the
user-space misses the update of a control value.

This patch corrects the behavior by properly returning 1 when the
value gets updated.
