This introduces a potential use-after-unlock or race because another thread concurrently modifies evf_mgr->ev_fence.

2025-05-16wifi: ath12k: Use scan link ID 15 for all scan operationsAditya Kumar Singh
According to the code documentation in ath12k_mac_op_hw_scan(), "if no links of an ML VIF are already active on the radio corresponding to the given scan frequency, the scan link (link ID 15) should be used". This rule should apply to non-ML interfaces as well to maintain uniformity across the driver. However, currently, link 0 is selected as the scan link during non-ML operations. Update the code to use scan link ID 15 in all cases.

2025-05-16wifi: ath12k: handle scan link during vdev createAditya Kumar Singh
For scanning purposes, the driver can use link ID 15 (scan link). A future change will make non-ML interfaces to select the scan link. In this scenario, arvif->link_id will be used to retrieve the link configuration in ath12k_mac_vdev_create(). However, link ID 15 is not recognized as a valid link ID in the upper kernel, which will result in a failure to fetch link_conf and subsequently cause the scan to fail. To avoid this issue, ensure link_conf is fetched only when the link ID is within the valid range. Since link_conf cannot be retrieved using the scan link, use vif->addr as the Ethernet address for creating the scan vdev. This address will serve as the source address (address 2) in the probe request frames during scanning. Additionally, use the automatic Tx power value for the vdev. As this is a scan vdev, these values do not affect the scan functionality. Note that vif->addr will only be taken when a valid link_conf can not be fetched. Otherwise, link_conf's address will be taken as address 2.

PTP capabilities are negotiated using virtchnl commands. There are two available modes of the PTP support: direct and mailbox. When the direct access to PTP resources is negotiated, virtchnl messages returns a set of registers that allow read/write directly. When the mailbox access to PTP resources is negotiated, virtchnl messages are used to access PTP clock and to read the timestamp values. Virtchnl API covers both modes and exposes a set of PTP capabilities. Using virtchnl API, the driver recognizes also HW abilities - maximum adjustment of the clock and the basic increment value.

Other than that, quirks for USB-audio and a few cosmetic fixes and changes in drivers that should be safe to apply" * tag 'sound-6.15-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: ALSA: usb-audio: Add sample rate quirk for Microdia JP001 USB Camera ALSA: es1968: Add error handling for snd_pcm_hw_constraint_pow2() ALSA: sh: SND_AICA should depend on SH_DMA_API ALSA: usb-audio: Add sample rate quirk for Audioengine D1 ALSA: ump: Fix a typo of snd_ump_stream_msg_device_info ALSA/hda: intel-sdw-acpi: Correct sdw_intel_acpi_scan() function parameter ALSA: seq: Fix delivery of UMP events to group ports
2025-05-16perf/arm-cmn: Initialise cmn->cpu earlierRobin Murphy
For all the complexity of handling affinity for CPU hotplug, what we've apparently managed to overlook is that arm_cmn_init_irqs() has in fact always been setting the *initial* affinity of all IRQs to CPU 0, not the CPU we subsequently choose for event scheduling. Oh dear.

2025-05-16ACPI: thermal: Execute _SCP before reading trip pointsArmin Wolf
As specified in section 11.4.13 of the ACPI specification the operating system is required to evaluate the _ACx and _PSV objects after executing the _SCP control method. Move the execution of the _SCP control method before the invocation of acpi_thermal_get_trip_points() to avoid missing updates to the _ACx and _PSV objects.

2025-05-16ACPI: OSI: Stop advertising support for "3.0 _SCP Extensions"Armin Wolf
As specified in section 5.7.2 of the ACPI specification the feature group string "3.0 _SCP Extensions" implies that the operating system evaluates the _SCP control method with additional parameters. However the ACPI thermal driver evaluates the _SCP control method without those additional parameters, conflicting with the above feature group string advertised to the firmware thru _OSI. Stop advertising support for this feature string to avoid confusing the ACPI firmware.

2025-05-16iommu: Clear the freelist after iommu_put_pages_list()Jason Gunthorpe
The commit below reworked how iommu_put_pages_list() worked to not do list_del() on every entry. This was done expecting all the callers to already re-init the list so doing a per-item deletion is not efficient. It was missed that fq_ring_free_locked() re-uses its list after calling iommu_put_pages_list() and so the leftover list reaches free'd struct pages and will crash or WARN/BUG/etc. Reinit the list to empty in fq_ring_free_locked() after calling iommu_put_pages_list(). Audit to see if any other callers of iommu_put_pages_list() need the list to be empty: - iommu_dma_free_fq_single() and iommu_dma_free_fq_percpu() immediately frees the memory - iommu_v1_map_pages(), v1_free_pgtable(), domain_exit(), riscv_iommu_map_pages() uses a stack variable which goes out of scope - intel_iommu_tlb_sync() uses a gather in a iotlb_sync() callback, the caller re-inits the gather Fixes: 13f43d7cf3e0 ("iommu/pages: Formalize the freelist API") Reported-by: Borah, Chaitanya Kumar <chaitanya.kumar.borah@intel.com> Closes: https://lore.kernel.org/r/SJ1PR11MB61292CE72D7BE06B8810021CB997A@SJ1PR11MB6129.namprd11.prod.outlook.com Tested-by: Borah, Chaitanya Kumar <chaitanya.kumar.borah@intel.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> Link: https://lore.kernel.org/r/0-v1-7d4dfa6140f7+11f04-iommu_freelist_init_jgg@nvidia.com Signed-off-by: Joerg Roedel <jroedel@suse.de>
2025-05-16clocksource/drivers/renesas-ostm: Unconditionally enable reprobe supportLad Prabhakar
Previously, the OSTM driver's platform probe path was only enabled for selected SoCs (e.g., RZ/G2L and RZ/V2H) due to issues on RZ/Ax (ARM32) SoCs, which encountered IRQ conflicts like: /soc/timer@e803b000: used for clock events genirq: Flags mismatch irq 16. 00215201 (timer@e803c000) vs. 00215201 (timer@e803c000) Failed to request irq 16 for /soc/timer@e803c000 renesas_ostm e803c000.timer: probe with driver renesas_ostm failed with error -16 These issues have since been resolved by commit 37385c0772a4 ("clocksource/drivers/renesas-ostm: Avoid reprobe after successful early probe"), which prevents reprobe on successfully initialized early timers. With this fix in place, there is no longer a need to restrict platform probing based on SoC-specific configs. This change unconditionally enables reprobe support for all SoCs, simplifying the logic and avoiding the need to update the configuration for every new Renesas SoC with OSTM. Additionally, the `ostm_of_table` is now marked with `__maybe_unused` to fix a build warning when `CONFIG_OF` is disabled. RZ/A1 and RZ/A2 remain unaffected with this change.

2025-05-16spi: spi-qpic-snand: extend FIELD_PREP() macro usageGabor Juhos
Large part of the code uses the FIELD_PREP() macro already to construct values to be written to hardware registers. Change the code to use also the macro for more registers of which the corresponding bitmasks are defined already. This makes the code more readable. It also syncs the affected codes with their counterparts in the 'qcom_nandc' driver, so it makes it easier to spot the differences between the two implementations. No functional changes intended.

Adding generic support for SoCs with tsens v1.0 IP with no RPM. Due to lack of RPM, tsens has to be reset and enabled in the driver init. SoCs can have support for more sensors than those which will actually be enabled. As such, init will only enable those explicitly added to the hw_ids array.
