Make sure each ASoC component is registered with a unique name.
The component is derived from the device name. If a device registers more
than one component, the component names will be the same.
This usually brings up a warning about the debugfs directory creation of
the component since directory already exists.
In such case, start numbering the component of the device so the names
don't collide anymore.

At the moment, querying the dai_name will stop of the first component
matching the dt node. This does not allow a device (single dt node) to
provide several ASoC components which could then be used through DT.
This change let the search go on if the xlate function of the component
returns an error, giving the possibility to another component to match
and return the dai_name.

Historically, CPU and Codec were implemented different, but now it is
merged as Component.
ALSA SoC is supporting suspend/resume at DAI and Component level.
The method is like below.
1) Suspend/Resume all CPU DAI if bus-control was 0
2) Suspend/Resume all Component
3) Suspend/Resume all CPU DAI if bus-control was 1
Historically 2) was Codec special operation.
Because CPU and Codec were merged into Component,
CPU suspend/resume has 3 chance to suspend(= 1/2/3), but
Codec suspend/resume has 1 chance (= 2).
Here, DAI side suspend/resume is caring bus-control, but no driver
which is supporting suspend/resume is setting bus-control.
This means 3) was never used.
Here, used parameter for suspend/resume component->dev and dai->dev are
same pointer.
For that reason, we can merge DAI and Component suspend/resume.
One note is that we should use 2), because it is caring BIAS level.
This patch removes 1) and 3).

soc-pcm is controlling it for activate DAI.
soc-core is controlling it for whole system
(= suspend/resume/probe/poweroff).
If we focus to soc-core side, it need to care about BIAS level.
Then, snd_soc_suspend() only is controlling it by Component base (a).
Other functions are DAI base (b).
(a) pinctrl_pm_select_xxx(component->dev, xxx);
(b) pinctrl_pm_select_xxx(dai->dev, xxx);
Because of these unbalance, the code is confusable.
Here, dai->dev and component->dev are same pointer.
Thus, we can replace it component base.

Current ALSA SoC is using struct snd_soc_rtdcom_list to
connecting component to rtd by using list_head.

struct list_head list; /* rtd::component_list */

struct snd_soc_pcm_runtime {

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(...)
{

It shows, it is possible to know how many components will be

The error path of soc_new_pcm_runtime() invokes soc_free_pcm_runtime()
that may cause a few problems. First off, it calls list_del() for
rtd->list that may not be initialized. Similarly,
snd_soc_pcm_component_free() traverses over the component list that
may not be initialized, either. Such access to the uninitialized list
head would lead to either a BUG_ON() or a memory corruption.
This patch fixes the access to uninitialized list heads by

via (A).
static void soc_cleanup_card_resources(struct snd_soc_card *card)
{
struct snd_soc_dai_link *link, *_link;
/* This should be called before snd_card_free() */
(A) soc_remove_link_components(card);
/* free the ALSA card at first; this syncs with pending operations */
if (card->snd_card) {
(B) snd_card_free(card->snd_card);
card->snd_card = NULL;
}
/* remove and free each DAI */
(X) soc_remove_link_dais(card);
for_each_card_links_safe(card, link, _link)
(C) snd_soc_remove_dai_link(card, link);
...
}
At (A), topology calls snd_soc_remove_dai_link().
Then topology rtd, and its related all data are freed.
Next, (B) is called, and then, pcm->private_free = soc_pcm_private_free()
is called.
static void soc_pcm_private_free(struct snd_pcm *pcm)
{
struct snd_soc_pcm_runtime *rtd = pcm->private_data;
/* need to sync the delayed work before releasing resources */
flush_delayed_work(&rtd->delayed_work);
snd_soc_pcm_component_free(rtd);
}
Here, it gets rtd via pcm->private_data.
But, topology related rtd are already freed at (A).
Normal sound card has no damage, becase it frees rtd at (C).
These are finalizing rtd related data.
Thus, these should be called when rtd was freed, not sound card
was freed. It is very natural and understandable.
In other words, pcm->private_free = soc_pcm_private_free()
is no longer needed.
Extra issue is that there is zero chance to call
soc_remove_dai() for topology related dai at (X).
Because (A) removes rtd connection from card too, and,
(X) is based on card connected rtd.
This means, (X) need to be called before (C) (= for normal sound)
and (A) (= for topology).
Now, I want to focus this patch which is the reason why
snd_card_free() = (B) is located there.
commit 4efda5f213
("ASoC: Fix use-after-free at card unregistration")
Original snd_card_free() was called last of this function.
But moved to top to avoid use-after-free issue.
The issue was happen at soc_pcm_free() which was pcm->private_free,
today it is updated/renamed to soc_pcm_private_free().
In other words, (B) need to be called before (C) (= for normal sound)
and (A) (= for topology), because it needs (not yet freed) rtd.
But, (A) need to be called before (B),
because it needs card->snd_card pointer.
If we call flush_delayed_work() and snd_soc_pcm_component_free()
(= same as soc_pcm_private_free()) when rtd was freed (= (C), (A)),
there is no reason to call snd_card_free() at top of this function.
It can be called end of this function, again.
But, in such case, it will likely break unbind again, as Takashi-san
reported. When unbind is performed in a busy state, the code may
release still-in-use resources.
At least we need to call snd_card_disconnect_sync() at the first place.
The final code will be...
static void soc_cleanup_card_resources(struct snd_soc_card *card)
{
struct snd_soc_dai_link *link, *_link;
if (card->snd_card)
(Z) snd_card_disconnect_sync(card->snd_card);
(X) soc_remove_link_dais(card);
(A) soc_remove_link_components(card);
for_each_card_links_safe(card, link, _link)
(C) snd_soc_remove_dai_link(card, link);
...
if (card->snd_card) {
(B) snd_card_free(card->snd_card);
card->snd_card = NULL;
}
}
To avoid release still-in-use resources,
call snd_card_disconnect_sync() at (Z).
(X) is needed for both non-topology and topology.
topology removes rtd via (A), and
non topology removes rtd via (C).
snd_card_free() is no longer related to use-after-free issue.
Thus, locating (B) is no problem.

soc_cleanup_card_resources() will call card->remove(), but it should be
called if card->probe() or card->late_probe() are called.
snd_soc_bind_card() might be error before calling
card->probe() / card->late_probe().
In that time, card->remove() will be called.
This patch adds card_probed parameter to judge it.

But, only soc_probe_aux_devices() case is indicating error at functions,

"topology added dai_link" (= (3)) are separated.
The code can be simple if we can bind dai_link when dai_link
is connected to *card list*.

soc_init_dai_link() is needed to be called before soc_bind_dai_link().

(1) is for (2), and (A) is for (B)
(1) and (2) are for card prelink dai_link.
(A) and (B) are for topology added dai_link.
soc_init_dai_link() is sanity check for dai_link, not initializing today.
Therefore, it is confusable naming. We can rename it as sanity_check.
And this check is for soc_bind_dai_link().
It can be more simple code if we can call it from soc_bind_dai_link().
This patch renames it to soc_dai_link_sanity_check(), and
call it from soc_bind_dai_link().

snd_soc_tplg_component_remove() is pair of snd_soc_tplg_component_load(),
and it is topology related cleanup function.
The driver which called _load() needs to call _remove() by its responsibility.
Today, skl-pcm and topology are the user, and these are calling both
_load() and _remove().
soc-core doesn't need to call it.
This patch remove it.

ALSA SoC has for_each_rtdcom() which is link list for
rtd-component which is called as rtdcom. The relationship image is like below
rtdcom rtdcom rtdcom
component component component
rtd->component_list -> list -> list -> list ...
Here, the pointer get via normal link list is rtdcom,
Thus, current for_each loop is like below, and need to get
component via rtdcom->component
for_each_rtdcom(rtd, rtdcom) {
component = rtdcom->component;
...
}
but usually, user want to get pointer from for_each_xxx is component
directly, like below.
for_each_rtd_component(rtd, rtdcom, component) {
...
}
This patch expands list_for_each_entry manually, and enable to get
component directly from for_each macro.
Because of it, the macro becoming difficult to read,
but macro itself becoming useful.

It is easy to read code if it is cleanly using paired function/naming,
like start <-> stop, register <-> unregister, etc, etc.
But, current ALSA SoC code is very random, unbalance, not paired, etc.
It is easy to create bug at the such code, and it will be difficult to
debug.
soc_cleanup_card_resources() (a) which is paired function of
snd_soc_instantiate_card() (A) is calling soc_remove_dai_links() (*)
to remove card related resources, but it is breaking
add/remove balance (B)(b)(C)(c)(D)(d), in other words
these should be called from soc_cleanup_card_resources() (a)
from balance point of view.
More headacke is that it is using original removing method for
dai_link even though we already have snd_soc_remove_dai_link()
which is the function for it (d).
This patch removes snd_soc_remove_dai_links() and balance up code.

Current rtd, rtd->dev, rtd->codec_dais are created by normal kzalloc(),
but we want to use devm_kzalloc() as much as possible.
Created rtd->dev is registered by device_register() at
soc_new_pcm_runtime(), and it will be freed at
soc_free_pcm_runtime() by device_unregister().
This means, if we can use devm_kzalloc(rtd->dev, xxx) for
rtd / rtd->codec_dais, all these are automatically freed
via soc_free_pcm_runtime().
This patch uses devm_kzalloc(rtd->dev, xxx) for rtd / rtd->codec_dais.

"rtd" is handled by soc_xxx_pcm_runtime(), and
"rtd->dev" is handled by soc_rtd_xxx().
There is no reason to separate these, and it makes code complex.
We can free these in the same time.
Here soc_rtd_free() (A) which frees rtd->dev is called from
soc_remove_link_dais() many times (1).
Then, it is using dev_registered flags to avoid multi kfree() (2).
This is no longer needed if we can merge these functions.
