ASoC: soc-core: setup card->rtd_num at snd_soc_instantiate_card()
card->rtd_num is used to count rtd. Initialize it at
snd_soc_instantiate_card() is very natural and less confusion.

ASoC: soc-core: use devm_xxx for component related resource
dai / component related resources are created when component is
registered, and it will be freed when component was unregistered.
These resources are not re-used after that.
This means, we can use devm_xxx for dai / component, without
thinking about kfree().
This patch uses devm_xxx for these.

ASoC: soc-core: remove soc_remove_dai_links()
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.

	static void soc_remove_dai_links(...)
	{
		...
(b)		soc_remove_link_dais(card);
(c)		soc_remove_link_components(card);

		for_each_card_links_safe(card, link, _link) {
			...
			/* it should use snd_soc_remove_dai_link() here */
(d)			list_del(&link->list);
		}
	}

(a)	static int soc_cleanup_card_resources(...)
	{
		...

		/* remove and free each DAI */

	{

		/* add predefined DAI links to the list */
		for_each_card_prelinks(card, i, dai_link)
(B)			snd_soc_add_dai_link(card, dai_link);
		...
		/* probe all components used by DAI links on this card */
(C)		ret = soc_probe_link_components(card);

		/* probe all DAI links on this card */
(D)		ret = soc_probe_link_dais(card);

ASoC: soc-core: use devm_kzalloc() for rtd
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.

ASoC: soc-core: merge soc_free_pcm_runtime() and soc_rtd_free()
"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.

	static void soc_remove_link_dais(...)
	{
		...
(1)		for_each_comp_order(order) {
(1)			for_each_card_rtds(card, rtd) {

(A)				soc_rtd_free(rtd);
				...
			}
		}
	}

(A)	static void soc_rtd_free(...)
	{
(2)		if (rtd->dev_registered) {
			/* we don't need to call kfree() for rtd->dev */
			device_unregister(rtd->dev);
(2)			rtd->dev_registered = 0;
		}
	}

This patch merges soc_rtd_free() into soc_free_pcm_runtime().

commit a0a4bf57a9 ("ASoC: core: delete component->card_list in soc_remove_component only")
was trying to fix a kernel oops when list_del was called twice without
re-init the list. Use list_del_init() can solve it, too. Besides, it
will be more readable if we cleanup all component related resource at

ASoC: soc-core: add snd_soc_dapm_init()
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-dapm has snd_soc_dapm_free() which cleanups debugfs, widgets, list.
But, there is no paired initialize function.
This patch adds snd_soc_dapm_init() and initilaizing dapm

ASoC: soc-core: dapm related setup at one place
Current ASoC setups some dapm related member at
snd_soc_component_initialize() which is called when component was
registered, and setups remaining member at soc_probe_component()
which is called when component was probed.
This kind of setup separation is no meanings, and it is very
difficult to read and confusable.
This patch setups all dapm settings at one place.

ASoC: soc-core: add NOTE to snd_soc_rtdcom_lookup()
We can find specified name component via snd_soc_rtdcom_lookup().
But, it is not enough under multi CPU/Codec/Platform, because many
components which have same driver name might be connected to same rtd.

Not using this function as much as possible is best solution,
but some drivers are already deeply depended to it.

We can expand this function, for example having "num" which specifies
found order at parameter, etc (In such case, it need to have fixed
probing order).
Or, use different driver name in such component, etc.

We will have such issue if multi CPU/Codec/Platform were supported.
To indicate it, this patch adds NOTE to this function.

ASoC: soc-core: use device_register()
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.

soc-core.c is using device_unregiser(), but there is no its paired
device_regiser(). We can find its code at soc_post_component_init()
which is using device_initialize() and device_add().
Here, device_initialize() + device_add() = device_register().

	-- linux/drivers/base/core.c --
	int device_register(struct device *dev)
	{
		device_initialize(dev);
		return device_add(dev);
	}

device_initialize() is doing each dev member's initialization only,
not related to device parent/release/groups.
Thus, we can postpone it.
let's use device_register() instead of device_initialize()/device_add().

ASoC: core: Move pcm_mutex up to card level from snd_soc_pcm_runtime
The pcm_mutex is used to prevent concurrent execution of snd_pcm_ops
callbacks. This works fine most of the cases but it can not handle setups
when the same DAI is used by different rtd, for example:
pcm3168a have two DAIs: one for Playback and one for Capture.
If the codec is connected to a single CPU DAI we need to have two dai_link
to support both playback and capture.

In this case the snd_pcm_ops callbacks can be executed in parallel causing
unexpected races in DAI drivers.

By moving the pcm_mutex up to card level this can be solved
while - hopefully - not breaking other setups.

ASoC: soc-core: support snd_soc_dai_link_component for aux_dev
To find aux_dev, ASoC is using .name, codec_name, codec_of_node.
Here, .name is used to fallback in case of no codec.

But, we already have this kind of component finding method by
snd_soc_dai_link_component and soc_find_component().
We shouldn't have duplicated implementation to do same things.
This patch adds snd_soc_dai_link_component support to finding aux_dev.

Now, no driver is using only .name.
All drivers are using codec_name and/or codec_of_node.
This means no driver is finding component from .name so far.
(Actually almost all drivers are using .name as just "device name",
 not for finding component...)

This patch
1) add snd_soc_dai_link_component support for aux_dev. legacy style will
   be removed if all drivers are switched to new style.
2) try to find component via snd_soc_dai_link_component.
   Then, it doesn't try to find via .name, because no driver is using
   it so far.
