ASoC: soc-core: fix always-false condition

The documentation for of_property_count_string reads

"
 * Returns the number of strings on
 * success, -EINVAL if the property does not exist, -ENODATA if property
 * does not have a value, and -EILSEQ if the string is not null-terminated
 * within the length of the property data.
"

Since the case for num_routes == 0 is not possible, let's remove this
test.

Merge series "ASoC: soc-pcm: ignore dummy-DAI at soc_pcm_params_symmetry()" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:
Hi Mark

I noticed if we have...

	1) Sound Card used DPCM
	2) It exchanges rate to 48kHz by using .be_hw_params_fixup()
	3) Codec had symmetric_rate = 1

We will get below error.
I didn't confirm, but maybe same things happen
if it exchanged channels/sample_bits.

ASoC: core: Don't set platform name when of_node is set
A DAI link has 3 components:
	* CPU
	* platform
	* codec(s)

A component is specified via:
	* name
	* of_node
	* dai_name

In order to avoid confusion when building a sound card we disallow
matching by both name and of_node (1).

soc_check_tplg_fes allows overriding certain BE links by overriding
BE link name. This doesn't work well if BE link was specified via DT,
because we end up with a link with both name and of_node specified
which is conflicting with (1).

In order to fix this we need to:
	* override of_node if component was specified via DT
	* override name, otherwise.

ASoC: soc-core: add comment for rtd freeing
We don't need to mind freeing for rtd,
because it was created from devm_kzalloc(dev, xxx) which is rtd->dev.

This means, if rtd->dev was freed, rtd will be also freed
automatically.

	soc_new_pcm_runtime(...)

		...

		rtd->dev = dev;

ASoC: soc-core: fix DMI handling
When DMI information is not present, trying to assign the card long
name results in the following warning.

WARNING KERN tegra-audio-graph-card sound: ASoC: no DMI vendor name!

The initial solution suggested was to test if the card device is an
ACPI one. This causes a regression visible to userspace on all Intel
platforms, with UCM unable to load card profiles based on DMI
information: the card devices are not necessarily ACPI ones, e.g. when
the parent creates platform devices on Intel devices.

To fix this problem, this patch exports the existing dmi_available
variable and tests it in the ASoC core.

ASoC: soc-core: Prevent warning if no DMI table is present
Many systems do not use ACPI and hence do not provide a DMI table. On
non-ACPI systems a warning, such as the following, is printed on boot.

 WARNING KERN tegra-audio-graph-card sound: ASoC: no DMI vendor name!

The variable 'dmi_available' is not exported and so currently cannot be
used by kernel modules without adding an accessor. However, it is
possible to use the function is_acpi_device_node() to determine if the
sound card is an ACPI device and hence indicate if we expect a DMI table
to be present. Therefore, call is_acpi_device_node() to see if we are
using ACPI and only parse the DMI table if we are booting with ACPI.

ASoC: core: Add common helper to parse aux devs from device tree
simple-card.c and meson-card-utils.c use pretty much the same
helper function to parse auxiliary devices from the device tree.

Make it easier for other drivers to parse these from the device tree
as well by adding a shared helper function to soc-core.c.

snd_soc_of_parse_aux_devs() is pretty much a copy of
meson_card_add_aux_devices() from meson-card-utils.c
with two minor changes:

  - Make property name configurable as parameter
  - Change dev_err() message slightly for consistency with other
    error messages in soc-core.c

ASoC: soc-core: Fix regression causing sysfs entries to disappear
The allocation order of things in soc_new_pcm_runtime was changed to
move the device_register before the allocation of the rtd structure.
This was to allow the rtd allocation to be managed by devm. However
currently the sysfs entries are added by device_register and their
visibility depends on variables within the rtd structure, this causes
the pmdown_time and dapm_widgets sysfs entries to be missing for all
rtds.

Correct this issue by manually calling device_add_groups after the
appropriate information is available.

ASoC: core: Remove only the registered component in devm functions
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.

ASoC: soc-link: introduce exit() callback
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.

ASoC: core: only convert non DPCM link to DPCM link
Additional checks for valid DAIs expose a corner case, where existing
BE dailinks get modified, e.g. HDMI links are tagged with
dpcm_capture=1 even if the DAIs are for playback.

This patch makes those changes conditional and flags configuration
issues when a BE dailink is has no_pcm=0 but dpcm_playback or
dpcm_capture=1 (which makes no sense).

As discussed on the alsa-devel mailing list, there are redundant flags
for dpcm_playback, dpcm_capture, playback_only, capture_only. This
will have to be cleaned-up in a future update. For now only correct
and flag problematic configurations.
