Merge tag 'acpi-5.15-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI fixes from Rafael Wysocki:
"These fix two regressions, one related to ACPI power resources
management and one that broke ACPI tools compilation.
Specifics:
- Stop turning off unused ACPI power resources in an unknown state to
address a regression introduced during the 5.14 cycle (Rafael
Wysocki).
- Fix an ACPI tools build issue introduced recently when the minimal
stdarg.h was added (Miguel Bernal Marin)"
* tag 'acpi-5.15-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
ACPI: PM: Do not turn off power resources in unknown state
ACPI: tools: fix compilation error
