of_get_next_child(ports, lnk). It will call of_node_put() inside. This

paired of_node_put(port0) when it quit function.

ASoC: Use *-y instead of *-objs in Makefile
Merge series from Takashi Iwai <tiwai@suse.de>:
This is a series of trivial cleanup patches for ASoC to correct
the *-objs suffix in Makefile. The other ALSA code has been covered
by a previous patch set
https://lore.kernel.org/r/20240507135513.14919-1-tiwai@suse.de
As was suggested in a patch review, *-objs suffix in Makefile is
basically a wrong use nowadays for kernel driver modules.
They should be replaced with *-y suffix instead.
This is a result of systematic conversions, separated per directory.

This patchset does not change any functionality, it just moves code

ASoC: SOF: Intel: discard SoundWire configuration if HDaudio codec is reported
The machine driver and topology selection starts with I2S, then
SoundWire and last uses HDaudio as a fallback. That assumes that the
ACPI information is correct but there are of course exceptions to the
rule.
On a Lenovo platform, an external HDaudio codec is detected, but the
ACPI tables expose TWO RT711 jack codecs. This patch skips the
SoundWire selection in case an external HDaudio codec is detected -
which only works with the additional assumption that no one will mix
HDaudio and SoundWire.

ASoC: codecs: Drop explicit initialization of struct i2c_device_id::driver_data to 0
These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.
ASoC: Use inline function for type safety in snd_soc_substream_to_rtd()
A common pattern in sound drivers is getting 'struct snd_soc_pcm_runtime'
from 'struct snd_pcm_substream' opaque pointer private_data field with
snd_soc_substream_to_rtd(). However 'private_data' appears in several
other structures as well, including 'struct snd_compr_stream'. The
field might not hold the same type for every structure, although seems
the case at least for 'struct snd_compr_stream', so code can easily make
a mistake by using macro for wrong structure passed as argument.
Switch from macro to inline function, so such mistake will be build-time
detectable.

ASoC: Intel: avs: PCM code cleanup
Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:
A set of changes that aims to improve readability of cohesiveness of the
pcm code for the avs-driver.
Start off with a change that synchronizes DAI open/close - DAIs are
started up in ascending order yet their shutdown does not follow the
scheme - it is done in the ascending order too, rather than desceding
one. This patch is a dependency for the next one in line.
To align the HDAudio DAI startup/shutdown with the non-HDAudio
equivalents, relocate the code from component to DAI. The reason above
is a dependency stems from codec driver requirements - HDAudio code
found in sound/pci/hda/ expects substream->runtime->private_data to
point to a valid stream (HOST) pointer.
With the hard part done, the follow up changes update the existing code
to reduce it is complexity - removal of duplicates, renaming of
ambiguous functions and adding new fields to DAI-data object so that the
number of local variables and casts is reduced.

ASoC: Constify local snd_sof_dsp_ops
Merge series from Krzysztof Kozlowski <krzk@kernel.org>:
The core code does not modify the 'struct snd_sof_dsp_ops' passed via
pointer in various places, so this can be made pointer to const in few
places. This in turn allows few drivers to have the local (usually
static) 'struct snd_sof_dsp_ops' as const which increased code safety,
as it is now part of rodata.
Not all drivers can be made safer that way. Intel and AMD rely on
customizing that 'struct snd_sof_dsp_ops' before passing to SOF, so they
won't benefit. They don't lose anything., either.

ASoc: SOF: misc updates for 6.10
Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
Fixes when fw_lib_prefix is not set, updated error messages, improved
dmesg logs to SoundWire configurations not supported by ACPI
tables/topology and support for IEC61937 passthrough.

ASoC: Intel: updates for 6.10 - part5
Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
This patchset corrects a couple of mistakes corrected, improves
snd_soc_card allocation. The new functionality is mostly for
SoundWire platforms, with new SKUs for Dell and Acer, and support for
the Cirrus Logic bridge/sidecar amplifier topology.
ASoC: sunxi: DMIC: Add controls for adjusting the mic gains
The AllWinner H6 and later SoCs that sport a DMIC block contain a set of registers to control
the gain (left + right) of each of the four supported channels.
Add ASoC controls for changing each of the stereo channel gains using alsamixer and alike
ASoC: dt-bindings: tegra30-i2s: convert to dt schema
Convert NVIDIA Tegra30 I2S binding to DT schema and
add "clock-names" property used by multiple tegra i2s blocks
in arch/arm64/boot/dts/nvidia/tegra132.dtsi. This is not a
required property by the binding.
'struct snd_sof_dsp_ops' is not modified by core code, so it can be made
const for increased code safety.
