snd_soc_dapm_add_path() is using local variable "widgets[]", but it is
same as path->node[].
This is no meaning and duplicate operation. This patch removes "widgets[]".

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: Failed to add route SOURCE(*) -> SINK

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.

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.

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.

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.

The recent fix for DAPM to correct the kctl change notification by the
commit 5af82c81b2 ("ASoC: DAPM: Fix missing kctl change

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().

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.

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.

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

goto xxx_err;
...
return ret;
^ component_err:

| interface_err:

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

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.

Kernel-doc markups should use this format:
identifier - description
There is a common comment marked, instead, with kernel-doc
notation.
Some identifiers have different names between their prototypes
and the kernel-doc markup.

soc_pcm_open() does rollback when failed (A),
but, it is almost same as soc_pcm_close().
static int soc_pcm_open(xxx)
{
...
if (ret < 0)
goto xxx_err;
...
return 0;
^ config_err:
| ...

2) snd_soc_link_startup/shutdown()
3) snd_soc_component_module_get/put()

This patch is for 1) snd_soc_dai_startup/shutdown().

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.

Current soc-xxx are getting rtd from substream by
rtd = substream->private_data;
But, getting data from "private_data" is very unclear.
This patch adds asoc_substream_to_rtd() macro which is
easy to understand that rtd from substream.

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
structures are not destroyed if the card is unbound. The widgets
are cleared up on unbind, however if the card is rebound as the
snd_soc_dai_link structures are reused these pointers will be left at
their old values, causing access to freed memory.

soc-dapm.c :: snd_soc_dai_link_event_pre_pmu() / snd_soc_dai_link_event()
are directly updating dai->active without caring about
stream_active / component->active.
It is breaking xxx_active count balance.
This patch uses snd_soc_dai_action() for it.
