ASoC: soc-component: add mark for snd_soc_pcm_component_pm_runtime_get/put()
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:
 |		...
 |	rtd_startup_err:
(A)		...
 |	component_err:
 |		...
 v		return ret;
	}

The difference is
soc_pcm_close() 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_close() and rollback.

Now, soc_pcm_open/close() are handling
	1) snd_soc_dai_startup/shutdown()
	2) snd_soc_link_startup/shutdown()
	3) snd_soc_component_module_get/put()
	4) snd_soc_component_open/close()
=>	5) pm_runtime_put/get()

This patch is for 5) pm_runtime_put/get().

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 get() was
succeeded. If rollback needed, it will check rollback flag and marked
substream pointer.

One note here is that it cares *current* get() 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.

ASoC: soc-compress: add snd_compress_ops
Current snd_soc_component_driver has compr_ops, and each driver can
have callback via it. But, it is mainly created for ALSA, thus, it
doesn't have "component" as parameter.
Thus, each callback can't know it is called for which component.
Each callback currently is getting "component" by using
snd_soc_rtdcom_lookup() with driver name.

	--- ALSA SoC  ---
	...
	if (component->driver->compr_ops &&
	    component->driver->compr_ops->open)
=>		return component->driver->compr_ops->open(stream);
	...

	--- driver ---
	static int xxx_open(struct snd_compr_stream *stream)
	{
		struct snd_soc_pcm_runtime *rtd = stream->private_data;
=>		struct snd_soc_component *component = snd_soc_rtdcom_lookup(..);
		...
	}

It works today, but, will not work in the future if we support multi
CPU/Codec/Platform, because 1 rtd might have multiple same driver
name component.

To solve this issue, each callback need to be called with component.
We already have many component driver callbacks.
This patch adds new snd_compress_ops, and call it with "component".

	--- ALSA SoC  ---
	...
	if (component->driver->compress_ops->open)
=>		return component->driver->compress_ops->open(
			component, substream);
			~~~~~~~~~
	...

	--- driver ---
	static int xxx_open(struct snd_soc_component *component,
			    struct snd_compr_stream *stream)
	{
=>		/* it don't need to use snd_soc_rtdcom_lookup() */
		...
	}

ASoC: soc-core: remove snd_soc_rtdcom_list
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.

ASoC: core: Init pcm runtime work early to avoid warnings
There are cases where we fail before we reach soc_new_pcm which would
init the workqueue. When we fail we attempt to flush the queue which
generates warnings from the workqueue subsystem when we have not inited
the queue. Solution is to use a proxy function to get around this issue.

ASoC: soc-core: add for_each_rtd_components() and replace
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.

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: compress: Clarify the intent of current compressed ops handling
For callbacks configuring the state of the components (trigger,
set_params, ack and set_metadata) simplify the code a little and make
intention clearer by aborting as soon as an error is encountered. The
operation has already failed and there is nothing to be gained from
processing the callbacks on additional components. The operations
currently abort after the callbacks, so this simply shortens the
error path.

For callbacks returning information from the driver (copy,
get_metadata, pointer, get_codec_caps, get_caps and get_params)
only look for the first callback provided, currently the code will
call every callback only returning the information provided by the
last. Since we can only return one set of data, it makes no sense to
request the data from every component. Again this just makes the
currently supported feature set a little more clear.

ASoC: compress: make BE and FE order inline with dpcm
For some reason order of startup/hw_params/prepare are reversed
in dynamic compress usecase when compared to dpcm usecase. This is
a issue with platforms like QCOM where it expects the BE to be
initialized before FE.

Interestingly the compress trigger callback order is inline with dpcm.

Am not 100% sure why the compress audio case has been reversed.
This patch is making the order inline with dpcm.

If the reverse ordering is just co-incendental then this change
makes sense and will avoid inventing some new mechanism to cope
with ordering.

ASoC: compress: Only call free for components which have been opened
The core should only call free on a component if said component has
already had open called on it. This is not presently the case and most
compressed drivers in the kernel assume it will be. This causes null
pointer dereferences in the drivers as they attempt clean up for stuff
that was never put in place.

This is fixed by aborting calling open callbacks once a failure is
encountered and then during clean up only iterating through the
component list to that point.

This is a fairly quick fix to the issue, to allow backporting. There
is more refactoring to follow to tidy the code up a little.

ASoC: compress: Correct handling of copy callback
The soc_compr_copy callback is currently broken. Since the
changes to move the compr_ops over to the component the return
value is not correctly propagated, always returning zero on
success rather than the number of bytes copied. This causes
user-space to stall continuously reading as it does not believe
it has received any data.

Furthermore, the changes to move the compr_ops over to the
component iterate through the list of components and will call
the copy callback for any that have compressed ops. There isn't
currently any consensus on the mechanism to combine the results
of multiple copy callbacks.

To fix this issue for now halt searching the component list when
we locate a copy callback and return the result of that single
callback. Additional work should probably be done to look at the
other ops, tidy things up, and work out if we want to support
multiple components on a single compressed, but this is the only
fix required to get things working again.
