2025-06-10drm/vc4: fix infinite EPROBE_DEFER loopGabriel Dalimonte
`vc4_hdmi_audio_init` calls `devm_snd_dmaengine_pcm_register` which may return EPROBE_DEFER. Calling `drm_connector_hdmi_audio_init` adds a child device. The driver model docs[1] state that adding a child device prior to returning EPROBE_DEFER may result in an infinite loop.

2025-06-09scsi: error: alua: I/O errors for ALUA state transitionsRajashekhar M A
When a host is configured with a few LUNs and I/O is running, injecting FC faults repeatedly leads to path recovery problems. The LUNs have 4 paths each and 3 of them come back active after say an FC fault which makes 2 of the paths go down, instead of all 4. This happens after several iterations of continuous FC faults. Reason here is that we're returning an I/O error whenever we're encountering sense code 06/04/0a (LOGICAL UNIT NOT ACCESSIBLE, ASYMMETRIC ACCESS STATE TRANSITION) instead of retrying.

Currently storvsc_timeout is only used in storvsc_sdev_configure(), and 5s and 10s are used elsewhere. It turns out that rarely the 5s is not enough on Azure, so let's use storvsc_timeout everywhere. In case a timeout happens and storvsc_channel_init() returns an error, close the VMBus channel so that any host-to-guest messages in the channel's ringbuffer, which might come late, can be safely ignored.

SFQ has an assumption of always being able to queue at least one packet.

2025-06-09scsi: s390: zfcp: Ensure synchronous unit_addPeter Oberparleiter
Improve the usability of the unit_add sysfs attribute by ensuring that the associated FCP LUN scan processing is completed synchronously. This enables configuration tooling to consistently determine the end of the scan process to allow for serialization of follow-on actions. While the scan process associated with unit_add typically completes synchronously, it is deferred to an asynchronous background process if unit_add is used before initial remote port scanning has completed. This occurs when unit_add is used immediately after setting the associated FCP device online. To ensure synchronous unit_add processing, wait for remote port scanning to complete before initiating the FCP LUN scan.

2025-06-09scsi: iscsi: Fix incorrect error path labels for flashnode operationsAlok Tiwari
Correct the error handling goto labels used when host lookup fails in various flashnode-related event handlers: - iscsi_new_flashnode() - iscsi_del_flashnode() - iscsi_login_flashnode() - iscsi_logout_flashnode() - iscsi_logout_flashnode_sid() scsi_host_put() is not required when shost is NULL, so jumping to the correct label avoids unnecessary operations. These functions previously jumped to the wrong goto label (put_host), which did not match the intended cleanup logic. Use the correct exit labels (exit_new_fnode, exit_del_fnode, etc.) to ensure proper error handling. Also remove the unused put_host label under iscsi_new_flashnode() as it is no longer needed.

2025-06-09SPI: omap2-mcspi: Fix SPI CS behaviour aroundMark Brown
Merge series from Félix Piédallu <felix.piedallu@non.se.com>: These patches fix the behaviour of the SPI Chip Select of the OMAP2 MCSPI driver used on TI SoCs. The omap2-mcspi driver supports the use of multi mode (multichannel in TI documentation). In this mode, the CS is asserted and deasserted by the hardware. The multi mode is disabled for messages when cs_change=0 for all transfers (e.g when CS is kept asserted between transfers of a same message). The multi mode also needs to be disabled for messages when cs_change=1 on the last transfer (e.g when CS is kept asserted after the WHOLE message), and the message right after. Currently, that is not the case and it CS is deasserted by hardware when it shouldn't. This breaks peripheral drivers that send multiple messages with the CS asserted in between. Patch 1 ensures that multi mode is disabled when cs_change=1 on the last transfer of the message. Patch 2 ensures that multi mode is disable on a message following one with cs_change=1 on the last transfer. This is the case for the TPM TIS SPI driver that uses this logic for flow control purposes. Tested on an AM6442 platform with a TPM ST33HTPH2X32AHE4.

2025-06-09ARC: Replace __ASSEMBLY__ with __ASSEMBLER__ in the non-uapi headersThomas Huth
While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembly code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel. This can be very confusing when switching between userspace and kernelspace coding, or when dealing with uapi headers that rather should use __ASSEMBLER__ instead. So let's standardize on the __ASSEMBLER__ macro that is provided by the compilers now. This is a completely mechanical patch (done with a simple "sed -i" statement).

The custom swap function used in sort() was identical to the default built-in sort swap. Remove the custom swap function and passes NULL to sort(), allowing it to use the default swap function. This change reduces code size and improves performance, particularly when CONFIG_MITIGATION_RETPOLINE is enabled. With RETPOLINE mitigation, indirect function calls incur significant overhead, and using the default swap function avoids this cost. $ ./scripts/bloat-o-meter ./unwind.o.old ./unwind.o.new add/remove: 0/1 grow/shrink: 0/1 up/down: 0/-22 (-22) Function old new delta init_unwind_hdr.constprop 544 540 -4 swap_eh_frame_hdr_table_entries 18 - -18 Total: Before=4410, After=4388, chg -0.50% Signed-off-by: Yu-Chun Lin <eleanor15x@gmail.com> Signed-off-by: Vineet Gupta <vgupta@kernel.org>

2025-06-09drm/xe: GSM size should be constant on most platformsMatt Roper
On old Intel platforms, the size of the GSM (i.e., the stolen memory that holds the GGTT page table entries) could vary, so the driver needed to read the actual size from the PCI config space. However from Xe_HP onward, the GSM is now always guaranteed to be exactly 8MB (which translates to a 4GB GGTT address space); this is always true regardless of what the platform's much larger PPGTT address space is. The bspec doesn't document the PCI config space as being a valid way to query the size of the GSM after Xe_LP platforms, although so far it still seems to be giving us proper values for Xe_HP, Xe2, and Xe3. However we suspect that the config space will stop providing correct values on some upcoming platforms, so we should stop relying on it. Instead just use the hardcoded 8MB value as documented elsewhere in the bspec.

2025-06-09drm/i915: split out display register macros to a separate fileJani Nikula
This is a scripted split of the display related register macros from i915_reg.h to display/intel_display_regs.h. As a starting point, move all the macros that are only used in display code (or GVT). If there are users in core i915 code or soc/, or no users anywhere, keep the macros in i915_reg.h. This is done in groups of macros separated by blank lines, moving the comments along with the groups. Some manually picked macro groups are kept/moved regardless of the heuristics above. This is obviously a very crude approach. It's not perfect. But there are 4.2k lines in i915_reg.h, and its refactoring has ground to a halt. This is the big hammer that splits the file to two, and enables further cleanup.

2025-06-09drm/xe/ggtt: Seperate flags and address in PTE encodingMaarten Lankhorst
Pinning large linear display framebuffers is becoming a bottleneck. My plan of attack is doing a custom walk over the BO, this allows for easier optimization of consecutive entries.

Obtain the id from the root tile. Likely this can be hardcoded to 0, but use the clean solution of obtaining root id and doing that. to_xe_device(ggtt->tile) can also be easily replaced with xe.

2025-06-09pinctrl: tb10x: Drop of_match_ptr for ID tableKrzysztof Kozlowski
The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it might not be relevant here).

The next message can't use multi-mode because the CS will be briefly deasserted before the first transfer.
