ASoC: drop bogus container_of() error handling
Merge series from Johan Hovold <johan@kernel.org>:

The dev_to_sdw_dev() helper uses container_of() to return the containing
soundwire device structure of its pointer argument and will never
return NULL.

ASoC: codecs: pm4125: clean up bind() device reference handling
A recent change fixed a couple of device leaks on component bind failure
and on unbind but did so in a confusing way by adding misleading
initialisations at bind() and bogus NULL checks at unbind().

9747b22a41 ASoC: Updates for v6.19
This is a very large set of updates, as well as some more extensive
 cleanup work from Morimto-san we've also added a generic SCDA class
 driver for SoundWire devices enabling us to support many chips with
 no custom code.  There's also a batch of new drivers added for both
 SoCs and CODECs.
 
  - Added a SoundWire SCDA generic class driver, pulling in a little
    regmap work to support it.
  - A *lot* of cleaup and API improvement work from Morimoto-san.
  - Lots of work on the existing Cirrus, Intel, Maxim and Qualcomm
    drivers.
  - Support for Allwinner A523, Mediatek MT8189, Qualcomm QCM2290,
    QRB2210 and SM6115, SpacemiT K1, and TI TAS2568, TAS5802, TAS5806,
    TAS5815, TAS5828 and TAS5830.
 
 This also pulls in some gpiolib changes supporting shared GPIOs in the
 core there so we can convert some of the ASoC drivers open coding
 handling of that to the core functionality.

ASoC: codecs: Fix error handling in pm4125 audio codec driver
pm4125_bind() acquires references through pm4125_sdw_device_get() but
fails to release them in error paths and during normal unbind
operations. This could result in reference count leaks, preventing
proper cleanup and potentially causing resource exhaustion over
multiple bind/unbind cycles.

Calling path: pm4125_sdw_device_get() -> bus_find_device_by_of_node()
-> bus_find_device() -> get_device.

Found by code review.

ASoC: codecs: pm4125: Remove irq_chip on component unbind
Component bind uses devm_regmap_add_irq_chip() to add IRQ chip, so it
will be removed only during driver unbind, not component unbind.
A component unbind-bind cycle for the same Linux device lifetime would
result in two chips added.  Fix this by manually removing the IRQ chip
during component unbind.

ASoC: codecs: pm4125: Fix potential conflict when probing two devices
Qualcomm PM4125 codec is always a single device on the board, however
nothing stops board designers to have two of them, thus same device
driver could probe twice.

Device driver is not ready for that case, because it allocates
statically 'struct regmap_irq_chip' as non-const and stores during
component bind in 'irq_drv_data' member a pointer to per-probe state
container ('struct pm4125_priv').

Second component bind would overwrite the 'irq_drv_data' from previous
device probe, so interrupts would be executed in wrong context.

The fix makes use of currently unused 'struct pm4125_priv' member
'pm4125_regmap_irq_chip', but renames it to a shorter name.

ASoC: use snd_kcontrol_chip() instead of
Merge series from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

We would like to hide struct snd_soc_dapm_context from driver. So we need
cleanup code first. Current ASoC have very similar functions (A)(B).

	(A) snd_soc_kcontrol_component()
	(B) snd_soc_dapm_kcontrol_component()

(B) is using very picky way to get component but using it is necessary in
ASoC. But (A) is just wrapper function to snd_kcontrol_chip(), and directly
using it without wrapper is very common way on ALSA.

This patch-set doesn't merge patches for each vender etc, because it makes
backport difficult.

ASoC: codecs: pm4125: use snd_kcontrol_chip() instead of snd_soc_kcontrol_component()
We have very similar name functions (A)(B). Both gets component from
snd_kcontrol, but (A) is used in callback functions which is registered
through snd_soc_add_component_controls(), (B) is used through
snd_soc_dapm_new_widgets().

	(A) snd_soc_kcontrol_component()
	(B) snd_soc_dapm_kcontrol_component()

(B) is using very picky way to get component but using it is necessary in
ASoC. But (A) is just wrapper function to snd_kcontrol_chip(), and directly
using it without wrapper is very common way on ALSA.
To reduce confusions of similar function, let's use common way on (A).

ASoC: codecs: add new pm4125 audio codec driver
The audio codec is found in Qualcomm PM2250/PM4125 PMICs and is used on
platforms like Qualcomm QCM2290. It has soundwire interface and
corresponding RX and TX slave devices.

It has only two input channels: HPH left and right. The line output (LO)
is linked to HPHL so the hardware has some limitations regarding concurrent
playback via HPH and LO for instance.

The codec driver also uses WCD MBCH framework. The MBHC functionality is
implemented in a minimalistic way to enable IRQs and avoid different
issues with IRQs.
