Merge tag 'acpi-5.14-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI fixes from Rafael Wysocki: "These fix a recently broken Kconfig dependency and ACPI device reference counting in an iterator macro. Specifics: - Fix recently broken Kconfig dependency for the ACPI table override via built-in initrd (Robert Richter) - Fix ACPI device reference counting in the for_each_acpi_dev_match() helper macro to avoid use-after-free (Andy Shevchenko)" * tag 'acpi-5.14-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: utils: Fix reference counting in for_each_acpi_dev_match() ACPI: Kconfig: Fix table override from built-in initrd
