From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx> The ACPI general PM domain does not expect its runtime PM callbacks, acpi_subsys_runtime_suspend() and acpi_subsys_runtime_resume(), to be invoked at any point during system-wide suspend and resume, so make it express that expectation by setting power.strict_midlayer for devices that it is attached to. Also make it clear that flag when it detaches from those devices. Signed-off-by: Rafael J.
