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
