Modify snd_soc_add_component so it calls snd_soc_component_initialize
no longer and thus providing true two-step registration. Drivers may
choose to change component's fields before actually adding it to ASoC
subsystem.

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.

Bossart <pierre-louis.bossart@linux.intel.com>:
While experimenting and introducing errors in Baytrail topology files
until I got them right, I encountered multiple kernel oopses and
memory leaks. This is a first batch to harden the code, but we should
probably think of a tool to fuzz the topology...
Pierre-Louis Bossart (5):
ASoC: topology: fix kernel oops on route addition error
ASoC: topology: fix tlvs in error handling for widget_dmixer
ASoC: topology: use break on errors, not continue
ASoC: topology: factor kfree(se) in error handling
ASoC: topology: add more logs when topology load fails.

The ASoC devm_ functions that register a component
(devm_snd_soc_register_component and devm_snd_dmaengine_pcm_register) will
clean their component by running snd_soc_unregister_component.
snd_soc_unregister_component will then remove all the components for the
device that was used to register the component in the first place.
However, some drivers register several components (such as a DAI and a
dmaengine PCM) on the same device, and if the dmaengine PCM is registered
first, then the DAI will be cleaned up first and
snd_dmaengine_pcm_unregister will be called next.
snd_dmaengine_pcm_unregister will then lookup the dmaengine PCM component
on the device, and if there's one unregister that component and release its
dmaengine channels. That doesn't happen in practice though since the first
call to snd_soc_unregister_component removed all the components, so we
never get the chance to release the dmaengine channels.
In order to fix this, instead of removing all the components for a given
device, we can simply remove the component that was registered in the first
place. We should have the same number of component registration than we
have components, so it should work just fine.

Some machine drivers allocate or request resources with
snd_soc_link_init() phase of the card probe. These resources need to
be properly released when removing a card, and this patch suggests a
dual exit() callback.
The exit() is invoked in soc_remove_pcm_runtime(), which is not
completely symmetric with the init() invoked in soc_init_pcm_runtime().
Alternate solutions were considered, e.g. adding a .remove() callback
for the platform driver, but that's not symmetrical at all and would
be difficult to handle if there are more than one dailink implementing
an .init(). We looked also into using .remove_dai_link() callback, but
that would also be imbalanced.
Note that because of the error handling in snd_soc_bind_card(), which
jumps to probe_end, there is no way to guarantee the exit() is invoked
with resources allocated in the init(). Prior to releasing those
resources, implementations of the exit() callback shall check the
resources are valid.

The registration of DAIs may be done at two distinct times, once
during a component registration and later when loading a
topology. Since devm_ managed resources are freed in the reverse order
they were allocated, when a component starts unregistering DAIs by
walking through the DAI list, the memory allocated for the
topology-registered DAIs was freed already, which leads to 100%
reproducible KASAN use-after-free reports.
This patch suggests a new devm_ function to force the DAI list to be
updated prior to freeing the memory chunks referenced by the list
pointers.

We already have bit field to control snd_soc_card.
Let's add "probed" field on it instead of local variable.
One note here is that soc_cleanup_card_resources()
will be called as (A) formal cleanup or as (B) error handling,
thus, it needs to distinguish these.
In (A) case, card will have "instantiated" flag if all probe
callback functions were called without error.
Thus, snd_soc_unbind_card() is using it to judging card was probed.
But this this patch removes it, because it is no longer needed.

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.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.

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.

ALSA SoC is currently categorizing CPU/Codec DAIs,
and it works well.
But modern devices require more complex connections,
for example Codec to Codec, etc, and future devices will
enable to more complex connections.
Because of these background, CPU/Codec DAIs categorizing is
no longer good much to modern device.
Currently, rtd has both CPU/Codec DAIs pointer.
rtd->cpu_dais = [][][][][][][][][]
rtd->codec_dais = [][][][][][][][][]
This patch merges these into DAIs pointer.
rtd->dais = [][][][][][][][][][][][][][][][][][]
^cpu_dais ^codec_dais
|--- num_cpus ---|--- num_codecs --|

Inline with multiple codec DAI approach, add support to allocate,

that. Also add support to loop over multiple cpu_dai during
suspend and resume.
This is intended as a preparatory patch to eventually unify the CPU

We need to setup rtd->close_delayed_work_func.
It will be set at snd_soc_dai_compress_new() or soc_new_pcm().
But these setups close_delayed_work() which is same name /
same implemantaion, but different local code.
To reduce duplicate code, this patch moves it as
snd_soc_close_delayed_work() and share same code.

Current ALSA SoC is using struct snd_soc_rtdcom_list to
connecting component to rtd by using list_head.
struct snd_soc_rtdcom_list {
struct snd_soc_component *component;
struct list_head list; /* rtd::component_list */
};
struct snd_soc_pcm_runtime {
...
struct list_head component_list; /* list of connected components */
...
};
The CPU/Codec/Platform component which will be connected to rtd (a)
is indicated via dai_link at snd_soc_add_pcm_runtime()
int snd_soc_add_pcm_runtime(...)
{
...
/* Find CPU from registered CPUs */
rtd->cpu_dai = snd_soc_find_dai(dai_link->cpus);
...
(a) snd_soc_rtdcom_add(rtd, rtd->cpu_dai->component);
...
/* Find CODEC from registered CODECs */
(b) for_each_link_codecs(dai_link, i, codec) {
rtd->codec_dais[i] = snd_soc_find_dai(codec);
...
(a) snd_soc_rtdcom_add(rtd, rtd->codec_dais[i]->component);
}
...
/* Find PLATFORM from registered PLATFORMs */
(b) for_each_link_platforms(dai_link, i, platform) {
for_each_component(component) {
...
(a) snd_soc_rtdcom_add(rtd, component);
}
}
}
It shows, it is possible to know how many components will be
connected to rtd by using
dai_link->num_cpus
dai_link->num_codecs
dai_link->num_platforms
If so, we can use component pointer array instead of list_head,
in such case, code can be more simple.
This patch removes struct snd_soc_rtdcom_list that is only
of temporary value, and convert to pointer array.

To find codec_conf component, it is using dev_name, of_node.
But, we already has this kind of finding component method by
snd_soc_dai_link_component, and snd_soc_is_matching_component().
We shouldn't have duplicate implementation to do same things.
This patch adds snd_soc_dai_link_component support to find
codec_conf component.

soc-core.c has 2 #ifdef CONFIG_DMI, but we can merge these.
OTOH, soc.h has dmi_longname, but it is needed if CONFIG_DMI was defined.
In other words, It is not needed if CONFIG_DMI was not defined.
This patch tidyup these.

Now soc-core and soc-topology is using snd_soc_remove_dai_link().
It removes pcm_runtime (= rtd) and disconnect it from card.
The purpose is removing pcm_runtime, not dai_link.
This patch renames function name.

Now soc-core and soc-topology is using snd_soc_add_dai_link().
The abstract of this function is "create pcm_runtime from
dai_link information and connect it to card".
Thus, "add dai_link" is wrong/confusable naming.
