Current soc_unbind_aux_dev() implementation is very half,
thus it is very unreadable.
for_each_comp_order(order) {
for_each_card_auxs_safe(card, comp, _comp) {
(1) if (comp->driver->remove_order == order) {
...
=> soc_unbind_aux_dev(comp);
}
}
soc_unbind_aux_dev() itself is not related to remove_order (1).
And, it is called from soc_remove_aux_devices(), even though
its paired function soc_bind_aux_dev() is called from
snd_soc_instantiate_card().
It is very unbalance, and very difficult to understand.
This patch do
1) update soc_bind_aux_dev() to self contained
2) call it from soc_cleanup_card_resources() to make up balance

Current soc_probe_link_dais() (1) is called under probe_order (2),
and it will initialize dai_link related settings at *Last* turn (3)(B).
It is very complex code.
static int soc_probe_link_dais(..., order)
{
(A) /* probe DAIs here */
...
(3) if (order != SND_SOC_COMP_ORDER_LAST)
return 0;
(B) /* initialize dai_link related settings */
...
}
static int snd_soc_instantiate_card(...)
{
...
(2) for_each_comp_order(order) {
for_each_card_rtds(...) {
(1) ret = soc_probe_link_dais(..., order);
}
}
}
This patch separes soc_probe_link_dais() into "DAI probe" portion (A),
and dai_link settings portion (B).
The later is named as soc_link_init() by this patch.

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.

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().

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.

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.
