The commit 58a1fbbb2ee8 ("PM / PCI / ACPI: Kick devices that might have been reset by firmware"), made PCI's and ACPI's ->complete() callbacks to be assigned to a new API called pm_complete_with_resume_check(), which was introduced in the same change. Later it turned out that using pm_complete_with_resume_check() isn't good enough for PCI, as it needs additional PCI specific checks, before deciding whether runtime resuming the device is needed when running the ->complete() callback. This leaves ACPI being the only user of pm_complete_with_resume_check(). Therefore let's restore ACPI's acpi_subsys_complete(), which was dropped in commit 58a1fbbb2ee8 ("PM / PCI / ACPI: Kick devices that might have been reset by firmware"). This enables us to remove the pm_complete_with_resume_check() API in a following change, but it also enables ACPI to add more ACPI specific checks in acpi_subsys_complete() if it turns out that is needed.
