Pull ACPI updates from Rafael Wysocki: "These include a couple of fixes, a new ACPI backlight quirk for Apple MacbookPro11,2 and Air7,2 and a bunch of cleanups: - Fix _CPC register setting issue for registers located in memory in the ACPI CPPC library code (Lifeng Zheng) - Use DEFINE_SIMPLE_DEV_PM_OPS in the ACPI battery driver, make it use devm_ for initializing mutexes and allocating driver data, and make it check the register_pm_notifier() return value (Thomas Weißschuh, Andy Shevchenko) - Make the ACPI EC driver support compile-time conditional and allow ACPI to be built without CONFIG_HAS_IOPORT (Arnd Bergmann) - Remove a redundant error check from the pfr_telemetry driver (Colin Ian King) - Rearrange the processor_perflib code in the ACPI processor driver to avoid compiling x86-specific code on other architectures (Arnd Bergmann) - Add adev NULL check to acpi_quirk_skip_serdev_enumeration() and make UART skip quirks work on PCI UARTs without an UID (Hans de Goede) - Force native backlight handling Apple MacbookPro11,2 and Air7,2 in the ACPI video driver (Jonathan Denose) - Switch several ACPI platform drivers back to using struct platform_driver::remove() (Uwe Kleine-König) - Replace strcpy() with strscpy() in multiple places in the ACPI subsystem (Muhammad Qasim Abdul Majeed, Abdul Rahim)" * tag 'acpi-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (24 commits) ACPI: video: force native for Apple MacbookPro11,2 and Air7,2 ACPI: CPPC: Fix _CPC register setting issue ACPI: Switch back to struct platform_driver::remove() ACPI: x86: Add adev NULL check to acpi_quirk_skip_serdev_enumeration() ACPI: x86: Make UART skip quirks work on PCI UARTs without an UID ACPI: allow building without CONFIG_HAS_IOPORT ACPI: processor_perflib: extend X86 dependency ACPI: scan: Use strscpy() instead of strcpy() ACPI: SBSHC: Use strscpy() instead of strcpy() ACPI: SBS: Use strscpy() instead of strcpy() ACPI: power: Use strscpy() instead of strcpy() ACPI: pci_root: Use strscpy() instead of strcpy() ACPI: pci_link: Use strscpy() instead of strcpy() ACPI: event: Use strscpy() instead of strcpy() ACPI: EC: Use strscpy() instead of strcpy() ACPI: APD: Use strscpy() instead of strcpy() ACPI: thermal: Use strscpy() instead of strcpy() ACPI: battery: Check for error code from devm_mutex_init() call ACPI: EC: make EC support compile-time conditional ACPI: pfr_telemetry: remove redundant error check on ret ...
