Wysocki <rafael.j.wysocki@intel.com> Scratch this, sorry. The code is correct as is, because the bus type doesn't provide ->complete at all in which case the core will run the driver's callback directly. We'll probably need ->complete for PCI at one point, but then I'll resubmit this one with a different changelog.
