2 dayshwmon: (asus_rog_ryujin) Add ROG Ryujin III 360Zac Lanzon
Add the USB product ID of the base ASUS ROG RYUJIN III 360 (0b05:1aa2, USB product string "ROG RYUJIN III"). It uses the same status report layout and cooler duty channel as the RYUJIN III EXTREME, EVA and WHITE editions, so it can share rog_ryujin_iii_info. Tested on a ROG RYUJIN III 360: coolant temperature, pump speed and internal fan speed report plausible values that track load, and the internal fan follows pwm2 (30% -> 870 RPM, 40% -> 1590 RPM).

2 dayshwmon: (asus-ec-sensors) add ROG STRIX Z490-A GAMINGMario Nuevo
The ROG STRIX Z490-A GAMING and Z490-F GAMING are essentially the same board apart from the F's onboard WiFi module, which isn't wired through the EC, so they share the same EC sensor layout. The Z490-A exposes the same EC sensor set as the Z490-F (chipset, CPU, motherboard, T_Sensor and VRM temperatures plus CPU_OPT and VRM HS fans) at the same EC registers, so reuse the Z490-F board_info for it.

2 dayshwmon: (pmbus/tps53679) Add support for TPS53622 and TPS53659Sanman Pradhan
TPS53622 and TPS53659 are dual-channel D-CAP+ step-down controllers that use the VID VOUT format and VOUT_MODE identification like the existing TPS53679/TPS53688, so they reuse tps53679_identify(). Shorten the Kconfig prompt to the family name and list the supported chips in the help text instead; this also adds TPS53685, which is already supported by the driver but was missing from the list. Update the driver documentation, including the per-attribute lists, and fix an existing "TPS53588" typo (should be TPS53688) in those lists.

2 dayshwmon: Add Minisforum UM780 XTX EC monitoring and fan controlSebastián Peyrott
Add a DMI-gated hwmon driver for the embedded controller used by the Minisforum UM780 XTX with board revision 1.1 and BIOS 1.06. Expose the CPU and system fan control temperatures and tachometers. The tachometer protocol returns one byte per OEM command, so serialize transactions and use high-low-high sampling to reject torn values. Allow selecting either complete OEM CPU fan profile through pwm1_enable and changing the two validated system fan transition temperatures through standard automatic-curve attributes. Cache coherent settings and restore them after the firmware reloads defaults following resume.

2 dayshwmon: (spd5118) Select page 0 unconditionally during probeArmin Wolf
Some Intel i2c controllers can be configured by the BIOS to reject writes to the SPD device. This often causes problems when the register page needs to be changed, usually during resume. Avoid probing on affected devices by unconditionally selecting page 0 by writing the SPD5118_REG_I2C_LEGACY_MODE register during probe. This will fail on affected controllers and thus prevent the driver from probing.

2 dayshwmon: (asus-ec-sensors) add ROG STRIX X670E-A GAMING WIFIAsai Neko
The ROG STRIX X670E-A GAMING WIFI is missing from the driver's DMI table. Consequently, the board lookup fails with -ENODEV, asus_ec_sensors does not load, and no asusec hwmon device or EC temperature readings are available. The board uses the same EC sensors, access mutex, and AMD 600-series register layout as the ROG STRIX X670E-E GAMING WIFI. Add its DMI entry using the existing X670E-E board information and document the board as supported. Before the change, there was no asusec device under /sys/class/hwmon and there were no EC readings. After the change, the driver registered four sensors with representative readings of 57-61 C for CPU, 68-71 C for CPU package, 43-44 C for motherboard, and 49-52 C for VRM. The readings correlated with nct6775 and k10temp. Repeated polling with both hwmon drivers loaded produced no EC access, bank-switch, concurrent access, or locking errors. Tested on an ASUS ROG STRIX X670E-A GAMING WIFI with BIOS 2704.

2 dayshwmon: (it87) prepare for extended PWM temp mapsbenoit.masson
Introduce helper logic for PWM-to-temperature mappings so newer register layouts can be supported while retaining the legacy two groups of three temperature sources. Honor the four global temperature sources on IT8603E and IT8622E instead of applying the legacy grouping to those chips. Use per-chip masks and shifts for newer extended mappings. Newer controllers keep the duty cycle in a separate register, so write their temperature mapping in both manual and automatic mode. This keeps the selected mapping across cache refreshes and mode changes. On older controllers, defer mapping writes while in manual mode and apply the cached mapping when switching to automatic mode.

3 daysrust_binder: reschedule node refcount update on thread exitAlice Ryhl
When a thread exits via BINDER_THREAD_EXIT, its pending work items are cancelled. If a thread exits while holding a pending node refcount increment (e.g. pushed as deferred work to that thread), the refcount increment was previously dropped because Node::cancel() and NodeWrapper::cancel() were no-ops. Dropping the refcount update leaves the node's delivery state and count state desynchronized, and userspace will not receive the notification, which can cause the node to never be freed from the process's nodes tree when all external references are dropped. Fix this by implementing DeliverToRead::cancel() for Node and NodeWrapper to move the pending refcount update to the process's work queue on thread exit so another thread can deliver it to userspace.

3 daysbinderfs: fix UAF write in binder_add_devicePeiyang He
binderfs_binder_device_create() publishes the new dentry with d_make_persistent() and then calls simple_done_creating(), which drops the parent directory lock and the creator's dentry reference. It then calls binder_add_device() to register the device in the global binder_devices list. After simple_done_creating() releases the parent directory lock, a concurrent unlinkat() can remove the new device entry. Dropping the creator's dentry reference can then trigger binderfs_evict_inode(), freeing the device. binder_add_device() later accesses the freed object, causing UAF write.

3 daysbinder: fix is_failure flag for superseded transaction cleanupTomer Pomeranc
When a TF_UPDATE_TXN transaction supersedes a pending async transaction, binder_release_entire_buffer() is called with is_failure=false. Since the superseded transaction was never delivered, binder_apply_fd_fixups() was never called and no fds were installed in the target process. With is_failure=false, the BINDER_TYPE_FDA cleanup handler interprets stale buffer contents as installed fd numbers and passes them to binder_deferred_fd_close(), closing unrelated file descriptors. Pass is_failure=true since the transaction was never delivered to the target, matching the semantics of all other undelivered-transaction cleanup paths.

3 daysbinder: fix leaked fd fixups on TF_UPDATE_TXN supersedeTomer Pomeranc
When a TF_UPDATE_TXN transaction supersedes a pending async transaction in a frozen process, the outdated transaction is freed with kfree() directly. This skips binder_free_txn_fixups(), leaking all binder_txn_fd_fixup entries and their fget()'d struct file references. The leaked file refcounts never reach zero, so the struct file objects are permanently pinned in memory. They survive process exit and accumulate across invocations until file-max exhaustion. Every other transaction cleanup path (binder_free_transaction(), binder_transaction() error paths, binder_release_work()) correctly calls binder_free_txn_fixups(). Add the missing call before kfree() in the t_outdated cleanup block.

3 daysusb: cdns3: fix use-after-free in cdns3_gadget_exit()Fan Wu
cdns3_gadget_start() arms two works on system_freezable_wq: pending_status_wq for the deferred ep0 status stage and aligned_buf_wq for realigned request buffers. Both handlers use the cdns3_device the works are embedded in, and cdns3_pending_setup_status_handler() also calls the ep0 request completion. cdns3_gadget_exit() does not wait for these works. It frees all endpoints and aligned buffers and drops the last reference to the gadget device, which frees priv_dev, so a work queued before the exit can run after the free. Fix this by waiting for both works after the gadget driver is unbound and the IRQ is freed, when no new work can be queued, and before the endpoints and buffers are released.

3 daysspi: spi-zynqmp-gqspi: stop the controller on shutdownItai Handler
The driver has no ->shutdown, and platform_drv_shutdown() has no fallback of its own. Unlike pci_device_shutdown(), which clears bus mastering when kexec_in_progress, nothing on the platform bus disarms a device that can still write to memory. The normal kexec path never calls ->suspend either, so the quiesce in zynqmp_qspi_suspend() is not reached. A controller that is still executing a DMA read may therefore keep writing to memory across a kexec. QSPIDMA_DST_ADDR still points at memory owned by the kernel that called kexec, DST_SIZE is non-zero and the flash is still clocked, so data can keep landing in RAM while the new kernel is being relocated, and after it has started executing. That destination is a physical address which means nothing to the new kernel, so the writes can corrupt whatever now occupies it: kernel text or data, page tables, or the initrd. Nothing reports an error and the resulting behaviour is undefined. This can be observed by reading GQSPI_EN (offset 0x114) and QSPIDMA_DST_ADDR/SIZE/STS/CTRL (offsets 0x800 to 0x80c) early in the new kernel, before the driver probes: without this patch GQSPI_EN reads 1 and QSPIDMA_DST_ADDR still points into the previous kernel's memory. Add a ->shutdown that stops the controller the way zynqmp_qspi_suspend() already does. spi_controller_suspend() stops the queue, waits for a message that is already executing and makes any later transfer fail with -ESHUTDOWN, so nothing can be cut short by the register write that follows. It may sleep, which is fine here: device_shutdown() runs in process context. Unlike ->suspend this cannot abort on error, because a controller left mastering the bus is worse than a truncated transfer, so a failure to drain is only logged. GQSPI_EN_OFST is then cleared, as zynqmp_qspi_remove() and zynqmp_qspi_suspend() already do. Skip that write only when pm_runtime_get_if_in_use() returns 0, i.e. runtime suspended: the clocks are gated, so the registers are unreachable and the controller cannot be mastering the bus. A negative return is not the same thing - it is what the CONFIG_PM=n stub always returns, and there probe() has enabled pclk and refclk for good, so the controller is running and must be stopped.

3 dayspinctrl: single: free the IRQ on domain creation failureMyeonghun Pak
pcs_irq_init_chained_handler() requests a shared IRQ on affected SoCs, but its domain creation failure path only removes a chained handler. That does not release the action installed by request_irq(). The probe can continue without interrupt support while leaving the shared IRQ action registered. Use pcs_irq_free() to undo the appropriate type of handler registration. At this point pcs->domain is NULL, so the helper only releases the parent IRQ handler. Then mark the IRQ invalid, as the other initialization error paths already do, to prevent another release from a later probe unwind or remove.
