2025-09-23Merge tag 'apple-soc-drivers-6.18' of ↵Arnd Bergmann
https://git.kernel.org/pub/scm/linux/kernel/git/sven/linux into soc/drivers Apple SoC driver updates for 6.18 Krzysztof Kozlowski asked us to move away from generic compatibles: - Adjust all dt-bindings to use apple,t8103-XXXX instead of apple,XXXX as fallback and add a comment that the old generic list should no longer be extended. - Add new fallback compatibles to pinctrl, pmdomain, spi, and mca drivers. These changes have been Acked by their subsystem maintainers to be merged through our tree together with the dt-bindings. Support for pre-M1 Apple Silicon: - SART and mailbox gain support for Apple's A11, which are both required for NVMe. - NVMe also gains support for Apple's A11 and the nvme maintainers prefer that we merge this through the soc tree together with the mailbox and SART changes. - SPMI compatibles for A11 and T2 have been added, also going through the soc tree due to conflicts with the generic compatible removal and because no driver change is required.

2025-09-23ASoC: wcd934x: fix error handling in wcd934x_codec_parse_data()Ma Ke
wcd934x_codec_parse_data() contains a device reference count leak in of_slim_get_device() where device_find_child() increases the reference count of the device but this reference is not properly decreased in the success path. Add put_device() in wcd934x_codec_parse_data() and add devm_add_action_or_reset() in the probe function, which ensures that the reference count of the device is correctly managed. Memory leak in regmap_init_slimbus() as the allocated regmap is not released when the device is removed. Using devm_regmap_init_slimbus() instead of regmap_init_slimbus() to ensure automatic regmap cleanup on device removal. Calling path: of_slim_get_device() -> of_find_slim_device() -> device_find_child(). As comment of device_find_child() says, 'NOTE: you will need to drop the reference with put_device() after use.'.

2025-09-23Support reading Subsystem ID from Device TreeMark Brown
Merge series from Stefan Binding <sbinding@opensource.cirrus.com>: In PC systems using ACPI, the driver is able to read back an SSID from the _SUB property. This SSID uniquely identifies the system, which enables the driver to read the correct firmware and tuning for that system from linux-firmware. Currently there is no way of reading this property from device tree. Add an equivalent property in device tree to perform the same role.
2025-09-23ALSA: usb-audio: don't apply interface quirk to Presonus S1824cRoy Vegard Ovesen
Testing with a Presonus STUDIO 1824c together with a Behringer ultragain digital ADAT device shows that using all 3 altno settings works fine. When selecting sample rate, the driver sets the interface to the correct altno setting and the correct number of channels is set. Selecting the correct altno setting via Ardour, Reaper or whatever other way to set the sample rate is more convenient than re-loading the driver module with device_setup to set altno.

2025-09-19ASoC: codecs: wcd93xxx: remove code duplicationMark Brown
Merge series from Srinivas Kandagatla <srinivas.kandagatla@oss.qualcomm.com>: All the Qualcomm WCD codecs and WCD based codecs have lots of code in common, resulting in lot of duplicate code. This series is an attempt to clean some of this by moving the common code to wcd-common library or to soundwire helper functions. Currently I have done cleanups for 4 codecs wcd934x, wcd937x, wcd938x and wcd939x, however any new Qualcomm codecs can avoid this duplication by using the wcd-common library. I have also added two helpers of_sdw_find_device_by_node() and sdw_slave_get_current_bank() in soundwire layer for the codecs to use them, this series was already acked by Soundwire maintainer Vinod. As original cleanup series was depending on the new soundwire interfaces I have combined both the series as they are cleaning up code duplications. As am touching the same codec drivers, 2 bug fixes are also added at the start of the series. There is still lot of code that is duplicate, but this is just a starting point for such cleanups. I have tested this on T14s, any testing is appreciated.

2025-09-18ASoC: fsl: fsl_qmc_audio: Only request completion on last channelChristophe Leroy
In non-interleaved mode, several QMC channels are used in sync. More details can be found in commit 188d9cae5438 ("ASoC: fsl: fsl_qmc_audio: Add support for non-interleaved mode.") At the time being, an interrupt is requested on each channel to perform capture/playback completion, allthough the completion is really performed only once all channels have completed their work. This leads to a lot more interrupts than really needed. Looking at /proc/interrupts shows ~3800 interrupts per second when using 4 capture and 4 playback devices with 5ms periods while only 1600 (200 x 4 + 200 x 4) periods are processed during one second. The QMC channels work in sync, the one started first is the one finishing first and the one started last is the one finishing last, so when the last one finishes it is guaranteed that the other ones are finished as well. Therefore only request completion processing on the last QMC channel. On my board with the above exemple, on a kernel started with 'threadirqs' option, the QMC irq thread uses 16% CPU time with this patch while it uses 26% CPU time without this patch.

2025-09-18ASoC: SOF: ipc3-dtrace: fix potential integer overflow in allocationSamasth Norway Ananda
Fix a potential integer overflow vulnerability in trace_filter_parse() where the allocation size calculation could overflow. The issue occurs when: 1. capacity is calculated by adding TRACE_FILTER_ELEMENTS_PER_ENTRY in a loop for each entry found in the input string. 2. capacity * sizeof(**out) multiplication could overflow if many entries are present in the input. 3. This results in a smaller allocation than expected, leading to potential buffer overflow. Replace kmalloc() with kmalloc_array() which provides built-in overflow checking and will safely fail the allocation if overflow would occur, preventing memory corruption.

Current soc-dapm is using "idle_bias_off", and its default settings came from snd_soc_component "idle_bias_on". It is complicated/confusable. Let's handling it as "idle_bias".

2025-09-18ASoC: soc-dapm: use dapm->component instead of container_of()Kuninori Morimoto
Because struct snd_soc_dapm_context is soc-dapm framework specific, user driver don't need to access its member directly, we would like to hide them. struct snd_soc_dapm_context will be removed from header in the future. Now, snd_soc_dapm_to_component() (A) will convert dapm to component by container_of() (a). (A) static inline struct snd_soc_component *snd_soc_dapm_to_component( struct snd_soc_dapm_context *dapm) { (a) return container_of(dapm, struct snd_soc_component, dapm); } dapm of component works, but dapm of card will be "unknown" pointer (= not NULL), because (a) is using "container_of()". OTOH, ASoC will call snd_soc_dapm_init() (X) to initialize dapm, and it will be called from snd_soc_bind_card() (p) (for card) or soc_probe_component() (q) (for component) with component pointer. (p) static int snd_soc_bind_card(...) { ... (X) snd_soc_dapm_init(..., NULL); ... ^^^^ } (q) static int soc_probe_component(...) { ... (X) snd_soc_dapm_init(..., component); ... ^^^^^^^^^ } And snd_soc_dapm_init() (X) will fill dapm->component (x) (X) void snd_soc_dapm_init(..., component, ...) { ... (x) dapm->component = component; ... } We can simply use dapm->component in snd_soc_dapm_to_component() (A). In this case, dapm of card (p) will be just NULL. Use dapm->component instead of container_of(). The picky note can be removed by this patch.

2025-09-18ASoC: SOF: ipc4-pcm: Fix incorrect comparison with number of tdm_slotsRichard Fitzgerald
In ipc4_ssp_dai_config_pcm_params_match() when comparing params_channels() against hw_config->tdm_slots the comparison should be a <= not a ==. The number of TDM slots must be enough for the number of required channels. But it can be greater. There are various reason why a I2S/TDM link has more TDM slots than a particular audio stream needs. The original comparison would fail on systems that had more TDM slots.

Check in snd_intel_dsp_check_soundwire() that the pointer returned by ACPI_HANDLE() is not NULL, before passing it on to other functions. The original code assumed a non-NULL return, but if it was unexpectedly NULL it would end up passed to acpi_walk_namespace() as the start point, and would result in [ 3.219028] BUG: kernel NULL pointer dereference, address: 0000000000000018 [ 3.219029] #PF: supervisor read access in kernel mode [ 3.219030] #PF: error_code(0x0000) - not-present page [ 3.219031] PGD 0 P4D 0 [ 3.219032] Oops: Oops: 0000 [#1] SMP NOPTI [ 3.219035] CPU: 2 UID: 0 PID: 476 Comm: (udev-worker) Tainted: G S AW E 6.17.0-rc5-test #1 PREEMPT(voluntary) [ 3.219038] Tainted: [S]=CPU_OUT_OF_SPEC, [A]=OVERRIDDEN_ACPI_TABLE, [W]=WARN, [E]=UNSIGNED_MODULE [ 3.219040] RIP: 0010:acpi_ns_walk_namespace+0xb5/0x480 This problem was triggered by a bugged DSDT that the kernel couldn't parse.

2025-09-17ALSA: usb: qcom: Fix false-positive address space checkTakashi Iwai
The sanity check previously added to uaudio_transfer_buffer_setup() assumed the allocated buffer being linear-mapped. But the buffer allocated via usb_alloc_coherent() isn't always so, rather to be used with (SG-)DMA API. This leaded to a false-positive warning and the driver failed to work. Actually uaudio_transfer_buffer_setup() deals only with the DMA-API addresses for MEM_XFER_BUF type, while other callers of uaudio_iommu_map() are with pages with physical addresses for MEM_EVENT_RING and MEM_XFER_RING types. So this patch splits the mapping helper function to two different ones, uaudio_iommu_map() for the DMA pages and uaudio_iommu_map_pa() for the latter, in order to handle mapping differently for each type. Along with it, the unnecessary address check that caused probe error is dropped, too.

2025-09-17ALSA: seq: Fix KCSAN data-race warning at snd_seq_fifo_poll_wait()Takashi Iwai
snd_seq_fifo_poll_wait() evaluates f->cells without locking after poll_wait(), and KCSAN doesn't like it as it appears to be a data-race. Although this doesn't matter much in practice as the value is volatile, it's still better to address it for the mind piece. Wrap it with f->lock spinlock for avoiding the potential data race.

2025-09-16ASoC: cs35l56: Handle vendor-specific UEFIMark Brown
Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>: This series adds handling for vendor-specific UEFI variables from Lenovo and HP. These vendors will switch to using their UEFI variables instead of the normal Cirrus Logic-defined mechanisms. The model of speaker fitted (Speaker ID) is normally signaled by a GPIO, and the driver is given access to this GPIO. Lenovo and HP will both stop giving the driver access to the GPIO and instead the BIOS will create a UEFI variable giving the value of the GPIO. HP will also start using their own UEFI variable to store amp calibration data. The content of the variable is the same as the Cirrus Logic variable, only the UEFI name and GUID are changed. Change in v2: Removed unused target_uid variable and code that set it in patch 6.
