Merge tag 'platform-drivers-x86-v5.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86
Pull x86 platform driver updates from Hans de Goede: "Highlights: - New think-lmi driver adding support for changing Lenovo Thinkpad BIOS settings from within Linux using the standard firmware- attributes class sysfs API - MS Surface aggregator-cdev now also supports forwarding events to user-space (for debugging / new driver development purposes only) - New intel_skl_int3472 driver this provides the necessary glue to translate ACPI table information to GPIOs, regulators, etc. for camera sensors on Intel devices with IPU3 attached MIPI cameras - A whole bunch of other fixes + device-specific quirk additions - New devm_work_autocancel() devm-helpers.h function" * tag 'platform-drivers-x86-v5.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86: (83 commits) platform/x86: dell-wmi-sysman: Change user experience when Admin/System Password is modified platform/x86: intel_skl_int3472: Uninitialized variable in skl_int3472_handle_gpio_resources() platform/x86: think-lmi: Move kfree(setting->possible_values) to tlmi_attr_setting_release() platform/x86: think-lmi: Split current_value to reflect only the value platform/x86: think-lmi: Fix issues with duplicate attributes platform/x86: think-lmi: Return EINVAL when kbdlang gets set to a 0 length string platform/x86: intel_cht_int33fe: Move to its own subfolder platform/x86: intel_skl_int3472: Move to intel/ subfolder platform/x86: intel_skl_int3472: Provide skl_int3472_unregister_clock() platform/x86: intel_skl_int3472: Provide skl_int3472_unregister_regulator() platform/x86: intel_skl_int3472: Use ACPI GPIO resource directly platform/x86: intel_skl_int3472: Fix dependencies (drop CLKDEV_LOOKUP) platform/x86: intel_skl_int3472: Free ACPI device resources after use platform/x86: Remove "default n" entries platform/x86: ISST: Use numa node id for cpu pci dev mapping platform/x86: ISST: Optimize CPU to PCI device mapping tools/power/x86/intel-speed-select: v1.10 release tools/power/x86/intel-speed-select: Fix uncore memory frequency display extcon: extcon-max8997: Simplify driver using devm extcon: extcon-max8997: Fix IRQ freeing at error path ...
