ASoC: dapm: use component prefix when checking widget names
On a TigerLake SoundWire platform, we see these warnings:

[   27.360086] rt5682 sdw:0:25d:5682:0: ASoC: DAPM unknown pin MICBIAS
[   27.360092] rt5682 sdw:0:25d:5682:0: ASoC: DAPM unknown pin Vref2

This is root-caused to the addition of a component prefix in the
machine driver. The tests in soc-dapm should account for a prefix
instead of reporting an invalid issue.

ASoC: dapm: remove widget from dirty list on free
A widget's "dirty" list_head, much like its "list" list_head, eventually
chains back to a list_head on the snd_soc_card itself. This means that
the list can stick around even after the widget (or all widgets) have
been freed. Currently, however, widgets that are in the dirty list when
freed remain there, corrupting the entire list and leading to memory
errors and undefined behavior when the list is next accessed or
modified.

I encountered this issue when a component failed to probe relatively
late in snd_soc_bind_card(), causing it to bail out and call
soc_cleanup_card_resources(), which eventually called
snd_soc_dapm_free() with widgets that were still dirty from when they'd
been added.

Merge series "ASoC: merge soc_pcm_hw_param() rollback and soc_pcm_hw_free()" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:
Hi Mark

soc_pcm_hw_params() does rollback when failed (A),
but, it is almost same as soc_pcm_hw_free().

	static int soc_pcm_hw_params(xxx)
	{
		...
		if (ret < 0)
			goto xxx_err;
		...
		return ret;

 ^	component_err:
 |		...
 |	interface_err:
(A)		...
 |	codec_err:
 |		...
 v		return ret;
	}

This kind of duplicated code can be a hotbed of bugs,
thus, this patch-set share soc_pcm_hw_free() and rollback.

Kuninori Morimoto (6):
  ASoC: soc.h: remove for_each_rtd_dais_rollback()
  ASoC: soc-pcm: move soc_pcm_hw_free() next to soc_pcm_hw_params()

ASoC: soc-dai: add mark for snd_soc_dai_hw_params/free()
soc_pcm_hw_params() does rollback when failed (A),
but, it is almost same as soc_pcm_hw_free().

	static int soc_pcm_hw_params(xxx)
	{
		...
		if (ret < 0)
			goto xxx_err;
		...
		return ret;

 ^	component_err:
 |		...
 |	interface_err:
(A)		...
 |	codec_err:
 |		...
 v		return ret;
	}

The difference is
soc_pcm_hw_free() is for all dai/component/substream,
rollback          is for succeeded part only.

This kind of duplicated code can be a hotbed of bugs,
thus, we want to share soc_pcm_hw_free() and rollback.

Now, soc_pcm_hw_params/free() are handling
	1) snd_soc_link_hw_params/free()
	2) snd_soc_pcm_component_hw_params/free()
=>	3) snd_soc_dai_hw_params/free()

This patch is for 3) snd_soc_dai_hw_params/free().

The idea of having bit-flag or counter is not enough for this purpose.
For example if one DAI is used for 2xPlaybacks for some reasons,
and if 1st Playback was succeeded but 2nd Playback was failed,
2nd Playback rollback doesn't need to call shutdown.
But it has succeeded bit-flag or counter via 1st Playback,
thus, 2nd Playback rollback will call unneeded shutdown.
And 1st Playback's necessary shutdown will not be called,
because bit-flag or counter was cleared by wrong 2nd Playback rollback.

To avoid such case, this patch marks substream pointer when hw_params() was
succeeded. If rollback needed, it will check rollback flag and marked
substream pointer.

One note here is that it cares *previous* hw_params() only now,
but we might want to check *whole* marked substream in the future.
This patch is using macro named "push/pop", so that it can be easily
update.

ASoC: dapm: don't call pm_runtime_* on card device
runtime_usage of sound card has been observed to grow without bound.
For example:
$ cat /sys/devices/platform/sound/power/runtime_usage
46
$ sox -n -t s16 -r 48000 -c 2 - synth 1 sine 440 vol 0.1 | \
  aplay -q -D hw:0,0 -f S16_LE -r 48000 -c 2
$ cat /sys/devices/platform/sound/power/runtime_usage
52

Commit 4e872a4682 ("ASoC: dapm: Don't force card bias level to be
updated") stops to force update bias_level on card.  If card doesn't
provide set_bias_level callback, the snd_soc_dapm_set_bias_level()
is equivalent to NOP for card device.

As a result, dapm_pre_sequence_async() doesn't change the bias_level of
card device correctly.  Thus, pm_runtime_get_sync() would be called in
dapm_pre_sequence_async() without symmetric pm_runtime_put() in
dapm_post_sequence_async().

Don't call pm_runtime_* on card device.

ASoC: soc-component: merge snd_soc_component_read() and snd_soc_component_read32()
We had read/write function for Codec, Platform, etc,
but these has been merged into snd_soc_component_read/write().

Internally, it is using regmap or driver function.
In read case, each styles are like below

regmap
	ret = regmap_read(..., reg, &val);

driver function
	val = xxx->read(..., reg);

Because of this kind of different style, to keep same read style,
when we merged each read function into snd_soc_component_read(),
we created snd_soc_component_read32(), like below.
commit 738b49efe6 ("ASoC: add snd_soc_component_read32")

(1)	val = snd_soc_component_read32(component, reg);

(2)	ret = snd_soc_component_read(component, reg, &val);

Many drivers are using snd_soc_component_read32(), and
some drivers are using snd_soc_component_read() today.

In generally, we don't check read function successes,
because, we will have many other issues at initial timing
if read function didn't work.

Now we can use soc_component_err() when error case.
This means, it is easy to notice if error occurred.

This patch aggressively merge snd_soc_component_read() and _read32(),
and makes snd_soc_component_read/write() as generally style.

This patch do
	1) merge snd_soc_component_read() and snd_soc_component_read32()
	2) it uses soc_component_err() when error case (easy to notice)
	3) keeps read32 for now by #define
	4) update snd_soc_component_read() for all drivers

Because _read() user drivers are not too many, this patch changes
all user drivers.

The newly added CODEC to CODEC DAI link widget pointers in
snd_soc_dai_link are better placed in snd_soc_pcm_runtime.
snd_soc_dai_link is really intended for static configuration of
the DAI, and the runtime for dynamic data.  The snd_soc_dai_link

are cleared up on unbind, however if the card is rebound as the

ASoC: dapm: fixup dapm kcontrol widget
snd_soc_dapm_kcontrol widget which is created by autodisable control
should contain correct on_val, mask and shift because it is set when the
widget is powered and changed value is applied on registers by following
code in dapm_seq_run_coalesced().

		mask |= w->mask << w->shift;
		if (w->power)
			value |= w->on_val << w->shift;
		else
			value |= w->off_val << w->shift;

Shift on the mask in dapm_kcontrol_data_alloc() is removed to prevent
double shift.
And, on_val in dapm_kcontrol_set_value() is modified to get correct
value in the dapm_seq_run_coalesced().

ASoC: dapm: Fix regression introducing multiple copies of DAI widgets
Refactoring was done to factor out the linking of DAI widgets into
a helper function, dapm_add_valid_dai_widget. However when this was
done, a regression was introduced for CODEC to CODEC links. It was
over looked that the playback and capture variables persisted across
all CODEC DAIs being processed, which ensured that the special DAI
widget that is added for CODEC to CODEC links was only created once.
This bug causes kernel panics during DAPM shutdown.

To stick with the spirit of the original refactoring whilst fixing the
issue, variables to hold the DAI widgets are added to snd_soc_dai_link.
Furthermore the dapm_add_valid_dai_widget function is renamed to
dapm_connect_dai_pair, the function only adds DAI widgets in the CODEC
to CODEC case and its primary job is to add routes connecting two DAI
widgets, making the original name quite misleading.

ASoC: export DPCM runtime update functions
This makes DPCM runtime update functions available for external
calling. As an example, virtualised ASoC component drivers may need
to call these when managing shared DAPM routes that are used by more
than one driver (i.e. when host driver and guest drivers have a DAPM
path from guest PCM to host DAI where some parts are owned by host
driver and others by guest driver).

ASoC: dapm: Correct DAPM handling of active widgets during shutdown
commit c2caa4da46 ("ASoC: Fix widget powerdown on shutdown") added a
set of the power state during snd_soc_dapm_shutdown to ensure the
widgets powered off. However, when commit 39eb5fd13d
("ASoC: dapm: Delay w->power update until the changes are written")
added the new_power member of the widget structure, to differentiate
between the current power state and the target power state, it did not
update the shutdown to use the new_power member.

As new_power has not updated it will be left in the state set by the
last DAPM sequence, ie. 1 for active widgets. So as the DAPM sequence
for the shutdown proceeds it will turn the widgets on (despite them
already being on) rather than turning them off.

Kuninori Morimoto 52645e332d
ASoC: soc-pcm: move dpcm_path_put() to soc-pcm.c
dpcm_path_put() (A) is calling kfree(*list).
The freed list is created by dapm_widget_list_create() (B) which is called
from snd_soc_dapm_dai_get_connected_widgets() (C) which is called from
dpcm_path_get() (D).

(B)	dapm_widget_list_create(**list, ...)
	{
		...
=>		*list = kzalloc();
		...
	}

(C)	snd_soc_dapm_dai_get_connected_widgets(..., **list, ...)
	{
		...
		dapm_widget_list_create(list, ...);
		...
	}

(D)	dpcm_path_get(..., **list)
	{
		...
		snd_soc_dapm_dai_get_connected_widgets(..., list, ...);
		...
	}

(A)	dpcm_path_put(**list)
	{
=>		kfree(*list);
	}

This kind of unbalance code is very difficult to read/understand.
To avoid this issue, this patch adds each missing paired function
dapm_widget_list_free()         for dapm_widget_list_create() (B), and
snd_soc_dapm_dai_free_widgets() for snd_soc_dapm_dai_get_connected_widgets() (C).

This patch uses these, and moves dpcm_path_put() next to dpcm_path_get().

ASoC: core: no need to check return value of debugfs_create functions
When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

Also, there is no need to store the individual debugfs file name, just
remove the whole directory all at once, saving a local variable.

Note, the soc-pcm "state" file has now moved to a subdirectory, as it is
only a good idea to save the dentries for debugfs directories, not
individual files, as the individual file debugfs functions are changing
to not return a dentry.
