In some SST deployments, administrators want to allow reading SST capabilities for non-root users. This can be achieved by changing file permissions for "/dev/isst_interface", but they still want to prevent any changes to the SST configuration by non-root users.

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.

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 ...

Members of struct software_node_ref_args should not be dereferenced directly but set using the provided macros. Commit d7cdbbc93c56 ("software node: allow referencing firmware nodes") changed the name of the software node member and caused a build failure. Remove all direct dereferences of the ref struct as a fix. However, this driver also seems to abuse the software node interface by waiting for a node with an arbitrary name "intel-xhci-usb-sw" to appear in the system before setting up the reference for the I2C device, while the actual software node already exists in the intel-xhci-usb-role-switch module and should be used to set up a static reference.

2025-10-28platform/x86: int3472: Fix double free of GPIO device during unregisterQiu Wenbo
regulator_unregister() already frees the associated GPIO device. On ThinkPad X9 (Lunar Lake), this causes a double free issue that leads to random failures when other drivers (typically Intel THC) attempt to allocate interrupts. The root cause is that the reference count of the pinctrl_intel_platform module unexpectedly drops to zero when this driver defers its probe. This behavior can also be reproduced by unloading the module directly. Fix the issue by removing the redundant release of the GPIO device during regulator unregistration.

This model was added as INTEL_PANTHERCOVE_X (based on the name of the core) with a comment that the platform name is Diamond Rapids. It was also placed at the end of the file in a new section for family 19 processors. This is different from previous naming as Andrew Cooper noted. PeterZ agreed and posted a patch[1] to fix the name and move it in sequence with other Xeon servers. But without a commit description or sign-off the patch wasn't ever applied. Patch updated to cover one additional use of the #define by turbostat and to change the "Family 6" comment to also list 18 and 19 since new models in these families are mixed in with family 6.
