Merge tag 'acpi-4.18-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI fix from Rafael Wysocki:
"Address a regression in ACPICA that ceased to clear the status of GPEs
and fixed events before entering the ACPI S5 (off) system state during
the 4.17 cycle which caused some systems to power up immediately after
they had been turned off"
* tag 'acpi-4.18-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
