ASoC: soc-pcm: indicate error message at dpcm_run_update_startup/shutdown()

Indicating error message when failed case is very useful for debuging.
In many case, its style is like below.

int function(...)
{
...
return ret;
}

int caller(...)
{
...
ret = function(...);
if (ret < 0)
dev_err(...)
...
}

This is not so bad, but in this style *each caller* needs to indicate
duplicate same error message, and some caller is forgetting to do it.
And caller can't indicate detail function() error information.

If function() indicates error message, we can get same and
detail information without forgot.

int function(...)
{
...
if (ret < 0)
dev_err(...)

return ret;
}

int caller(...)
{
...
ret = function(...);
...
}

1) remove duplicated ret = -EINVAL
2) remove blank line
do below to dpcm_run_update_shutdown()

Merge series "Fix reset controls and RPM of NVIDIA Tegra ASoC drivers" from Dmitry Osipenko <digetx@gmail.com>:

Hi,

This series adds missing hardware reset controls to I2S and AC97 drivers,
corrects runtime PM usage and drivers probe/remove order. Currently drivers
happen to work properly because reset is implicitly deasserted by tegra-clk
driver, but clk driver shouldn't touch the resets and we need to fix it
because this breaks other Tegra drivers. Previously we fixed the resets of
the AHUB and HDMI codec drivers, but turned out that we missed the I2C and
AC97 drivers.

Thanks to Paul Fertser for testing the pending clk patches and finding
that audio got broken on Tegra20 AC100 netbook because of the missing I2S
reset.

Changelog:

v5: - After taking another look at the drivers I noticed couple more
      things that could be improved. These new patches correct runtime PM
      and probe/remove order of the drivers:

        ASoC: tegra20: spdif: Correct driver removal order
        ASoC: tegra20: spdif: Remove handing of disabled runtime PM
        ASoC: tegra20: i2s: Add system level suspend-resume callbacks
        ASoC: tegra20: i2s: Correct driver removal order
        ASoC: tegra20: i2s: Use devm_clk_get()
        ASoC: tegra20: i2s: Remove handing of disabled runtime PM
        ASoC: tegra30: i2s: Correct driver removal order
        ASoC: tegra30: i2s: Use devm_clk_get()
        ASoC: tegra30: i2s: Remove handing of disabled runtime PM
        ASoC: tegra30: ahub: Reset global variable
        ASoC: tegra30: ahub: Correct suspend-resume callbacks
        ASoC: tegra30: ahub: Remove handing of disabled runtime PM

v4: - Added missing prototype for reset_control_bulk_put().

v3: - Fixed reset stubs for !CONFIG_RESET_CONTROLLER.

v2: - After some more testing I found that I2S control logic doesn't require
      I2S clock to be enabled for resetting. Hence it's fine to have I2S to
      be reset by parent AHUB driver, so I dropped "tegra30: i2s: Add reset
      control" patch.

    - While I was double-checking resets on Tegra30, I found that that
      Tegra30 I2S driver has a broken runtime PM which doesn't restore
      hardware state on resume and it's lost after AHUB RPM-resume.
      Thus, added this new patch "tegra30: i2s: Restore hardware state
      on runtime PM resume".

    - Added new patches which switch AHUB driver to use reset-bulk API.
      I took the RFC patch from Philipp Zabel, fixed it and added
      devm_reset_control_bulk_optional_get_exclusive_released() that
      will be useful for further Tegra GPU patches. This is a minor
      improvement which makes code cleaner.

Tegra30 I2S driver syncs regmap cache only on resume from system suspend,

AHUB driver resets the I2S hardware, hence h/w state is lost after each

ASoC: Intel: bytcr_rt5640: Add used AIF to the components string

Depending on which AIF is used the UCM profile needs to setup
a different path through the rt5640's "Digital Mixer Path" graph.

ATM the UCM profiles solve this by just enabling paths to the outputs /
from the input from both AIF1 and AIF2 and then relying on the DAPM
framework to power-down the parts of the graph connected to the
unused AIF.

But in order to be able to use hardware-volumecontrol and to use
the hardware mute controls, which are necessary for mute LED control,
the UCM profiles need to know which AIF is actually being used.

Add a new "aif:1" or "aif:2" part to the component string to provide
info about the used AIF to userspace / to the UCM profiles.

Note the size of byt_rt5640_components is not increased because the
size of 32 chars already is big enough.

ASoC: rt5640: Rename 'Mono DAC Playback Volume' to 'DAC2 Playback Volume'

Rename 'Mono DAC Playback Volume' to 'DAC2 Playback Volume' and move it
from rt5640_specific_snd_controls[] to rt5640_snd_controls[].

The RT5640_DAC2_DIG_VOL register controlled by this mixer-element has
nothing to do with the Mono (Amplified) output which is only available
on the ALC5640 chip and not on the ALC5642 chip.

The RT5640_DAC2_DIG_VOL volume-control is the main volume control for
audio coming from the I2S2 / AIF2 input of the chip and as such is also
available on the ALC5642.

This commit results in the following userspace visible changes:

1. On devices with an ACL5640 codec, the 'Mono DAC Playback Volume'
control is renamed to 'DAC2 Playback Volume' allowing the alsa-lib
mixer code to properly group it with the 'DAC2 Playback Switch' which
is controlling the mute bits in the RT5640_DAC2_DIG_VOL register.

Note the removal of the 'Mono DAC Playback Volume' is not an issue for
userspace because the UCM profiles do not use it (the UCM profiles are
shared betweent the 5640 and 5642 and only the 5640 had this control).

2. On devices with an ACL5642 codec, there now will be a new
'DAC2 Playback Volume', grouped with the 'DAC2 Playback Switch'

Having a complete 'DAC2 Playback Volume' / 'DAC2 Playback Switch' pair
on both variants will allow enabling hardware-volume control by
setting the UCM PlaybackMasterElem to "DAC2" on devices where the
I2S2/AIF2 interface of the codec is used.

These has no relationship to each other.

My 1 concern is [3/8] patch. I think it is no problem,
but I'm not 100% sure why current code was such code.
Pierre-Louis / Liam might about something.

v1 -> v2
- soc_cpu/codec_dai_name() is now inline function
- rename soc_pcm_care_symmetry() to soc_pcm_update_symmetry()

v2 -> v3
- log fix at [6/8]
  - Thus, it will be minus users at (2).
  + Thus, users will be a negative number at (2)

ASoC: soc-pcm: share DPCM BE DAI stop operation

soc-pcm has very similar but different DPCM BE DAI stop operation at
1) dpcm_be_dai_startup() error case rollback
2) dpcm_be_dai_startup_unwind()
3) dpcm_be_dai_shutdown()

The differences are
1) for rollback
2) Doesn't check by snd_soc_dpcm_be_can_update() (Is this bug ?)
3) Do soc_pcm_hw_free() if it was not !OPENed and !HW_FREEed,
   and call soc_pcm_close().

We can share same code by
1) hw_free is not needed. Needs last dpcm as rollback.
2) hw_free is not needed.
3) hw_free is     needed.

This patch adds new dpcm_be_dai_stop() and share these 3.

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.
