10 daysplatform/x86/intel/pmt/discovery: use valid device pointer in dev_err_probeAlok Tiwari
The PMT feature probe creates a child device with device_create(). If device creation fail, the code pass priv->dev (which is an ERR_PTR) to dev_err_probe(), which is not a valid device pointer. This patch change the dev_err_probe() call to use the parent auxiliary device (&auxdev->dev) and update the error message to reference the parent device name. It ensure correct error reporting and avoid passing an invalid device pointer.

10 daysplatform/x86: hp-bioscfg: Fix out-of-bounds array access in ACPI package parsingJunrui Luo
The hp_populate_*_elements_from_package() functions in the hp-bioscfg driver contain out-of-bounds array access vulnerabilities. These functions parse ACPI packages into internal data structures using a for loop with index variable 'elem' that iterates through enum_obj/integer_obj/order_obj/password_obj/string_obj arrays. When processing multi-element fields like PREREQUISITES and ENUM_POSSIBLE_VALUES, these functions read multiple consecutive array elements using expressions like 'enum_obj[elem + reqs]' and 'enum_obj[elem + pos_values]' within nested loops. The bug is that the bounds check only validated elem, but did not consider the additional offset when accessing elem + reqs or elem + pos_values. The fix changes the bounds check to validate the actual accessed index.

10 daysplatform/x86: samsung-galaxybook: Fix problematic pointer castArmin Wolf
A user reported that reading the charge threshold on his device results in very strange values (like 78497792) being returned. The reason for this seems to be the fact that the driver casts the int pointer to an u8 pointer, leaving the last 3 bytes of the destination uninitialized. Fix this by using a temporary variable instead.

git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux Pull gpio updates from Bartosz Golaszewski: "There's one new driver, lots of various updates to existing ones, some refactoring support for new models and misc tweaks and fixes. The biggest new feature in GPIO core is adding support for managed, enable-counted sharing of GPIO pins, something that - until now - was only hacked around with the GPIOD_FLAGS_BIT_NONEXCLUSIVE request flag which basically allowed drivers to "fight it out" for the descriptor and provided no synchronization. It was enabled on Qualcomm platforms (and thus is enabled on arm64 defconfig) and I plan on removing GPIOD_FLAGS_BIT_NONEXCLUSIVE once all drivers using it are switched to the new mechanism. GPIO core: - add proper support for shared GPIOs that's aiming to replace the current sharing mechanism (which provides no synchronization ot enable counting) and enable it for Qualcomm platforms - improve the software node GPIO lookup by using the fwnode representation instead of the software node's name which was prone to bugs (GPIO controllers don't have to use the software node's name as their kernel label) - remove the last user of legacy-of-mm-gpiochip.h and drop the header - move closer to removing the legacy gpio_request_one() routine - rename some symbols for consistency - shrink GPIO printk() helpers by reusing existing code - remove some redundant kernel messages - use min() instead of min_t() in GPIO ACPI code - use system_percpu_wq instead of system_wq in GPIO character device code New drivers: - add a driver for the QIXIS FPGA GPIO controller Driver improvements: - use modernized variants of power management macros across a wide array of drivers in order to avoid having to use the __maybe_unused attribute - convert gpio-elkhartlake and reset-gpio to using the auxiliary bus instead of the platform bus as they are not really described in firmware - use lock guards and update symbol prefixes in gpio-mmio - support the bryx radio interface kit in gpio-mpsse + refactor the driver - use software nodes for configuring the reset-gpio driver, including setting up the reference to the shared "reset" pin - check and propagate the return value of gpiod_set_value() to user-space in gpio-virtuser (this was previously not possible as this function returned void) - extend the gpio-regmap helper with more features (bypass cache for aliased inputs, force writes for aliased data registers, add a new configuration parameter) - remove unneeded includes from gpio-aspeed and gpio-latch - add support for Tegra410 to gpio-tegra186 - replace PCI-specific PM with generic device-level PM in gpio-bt8xx - use dynamic GPIO range allocation in gpio-loongson-64bit - improve handling of level-triggered interrupts in gpio-pca953x - add suspend/resume support to gpio-fxl6408 - add support for more models to gpio-menz127 - optimize gpio-mvebu interrupt handling by avoiding unnecessary calls to mvebu_gpio_irq_handler() - make locking more consistent in gpio-grgpio Device-tree bindings: - document new NXP and Microchip models Documentation: - add a comprehensive compatibility and feature list for gpio-pca953x, which is a great addition as it's probably the most commonly used GPIO expander driver - kernel-doc tweaks Late fixes: - use BYTE_CTRL_MODE for 2K2000/3000 models in gpio-loongson" * tag 'gpio-updates-for-v6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (80 commits) gpio: loongson: Switch 2K2000/3000 GPIO to BYTE_CTRL_MODE gpio: regmap: fix kernel-doc notation gpio: shared: fix a deadlock gpio: shared-proxy: set suppress_bind_attrs gpio: shared: ignore GPIO hogs when traversing the device tree gpio: shared: ignore special __symbols__ node when traversing device tree gpio: shared: handle the reset-gpios corner case gpio: zynq: Use modern PM macros gpio: xilinx: Use modern PM macros gpio: xgene: Use modern PM macros gpio: uniphier: Use modern PM macros gpio: tqmx86: Use modern PM macros gpio: pch: Use modern PM macros gpio: omap: Use modern PM macros gpio: msc313: Use modern PM macros gpio: mlxbf2: Use modern PM macros gpio: ml-ioh: Use modern PM macros gpio: pl061: Use modern PM macros gpio: htc-egpio: Use modern PM macros gpio: brcmstb: Use modern PM macros ...

2025-11-28platform: x86: replace use of system_wq with system_percpu_wqMarco Crivellari
This patch continues the effort to refactor workqueue APIs, which has begun with the changes introducing new workqueues and a new alloc_workqueue flag: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") The point of the refactoring is to eventually alter the default behavior of workqueues to become unbound by default so that their workload placement is optimized by the scheduler. Before that to happen after a careful review and conversion of each individual case, workqueue users must be converted to the better named new workqueues with no intended behaviour changes: system_wq -> system_percpu_wq system_unbound_wq -> system_dfl_wq This way the old obsolete workqueues (system_wq, system_unbound_wq) can be removed in the future.

2025-11-28platform/x86: lenovo-wmi-gamezone Use max-power rather than balanced-performanceDerek J. Clark
When developing the gamezone WMI drivers, "extreme mode" was matched to the performance platform profile and "performance" was matched to the balanced-performance platform profile, but only if extreme mode was fully supported; otherwise performance was matched to the "performance" platform profile. This has led to quite a bit of confusion with users not understanding why the LED color indicating the platform profile doesn't match their expectations. To solve this, replace the confusing convention by using the new max-power profile to represent "extreme mode". While add it, update the documentation to reflect the expected LED colors in each operating mode. Signed-off-by: Derek J.

2025-11-27platform/x86/amd/pmf: Refactor repetitive BIOS output handlingShyam Sundar S K
Replace repetitive switch-case statements for PMF_POLICY_BIOS_OUTPUT_* with a helper function and consolidated case handling. This reduces code duplication and improves maintainability. The 10 BIOS output policies (PMF_POLICY_BIOS_OUTPUT_1 through PMF_POLICY_BIOS_OUTPUT_10) previously each had individual case statements with identical logic. This patch introduces amd_pmf_get_bios_output_idx() to map policy values to array indices, consolidating the handling into a single case block with fallthrough. Also, add a new function amd_pmf_update_bios_output() to simplify the code handling. This approach handles non-sequential policy enum values gracefully and makes future additions easier to implement.

2025-11-21platform/x86: ayaneo-ec: Add controller power and modules attributesAntheas Kapenekakis
The Ayaneo 3 features hot-swappable controller modules. The ejection and management is done through HID. However, after ejecting the modules, the controller needs to be power cycled via the EC to re-initialize. For this, the EC provides a variable that holds whether the left or right modules are connected, and a power control register to turn the controller on or off. After ejecting the modules, the controller should be turned off. Then, after both modules are reinserted, the controller may be powered on again to re-initialize. This patch introduces two new sysfs attributes: - `controller_modules`: a read-only attribute that indicates whether the left and right modules are connected (none, left, right, both). - `controller_power`: a read-write attribute that allows the user to turn the controller on or off (with '1'/'0'). Therefore, after ejection is complete, userspace can power off the controller, then wait until both modules have been reinserted (`controller_modules` will return 'both') to turn on the controller.
