From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx> The pm_request_idle() in pm_generic_complete() is pointless as it is called with the runtime PM usage counter different from zero (bumped up by the core during the prepare phase of system suspend) and the core calls pm_runtime_put() for all devices after executing their complete callbacks, so drop it. This allows the PCI PM layer to use pm_generic_complete() too. Signed-off-by: Rafael J.
