This turns out to be harder than it looks. If an error occurs, we may run the complete callback for devices that never were suspended or resumed and hence never had their usage_count incremented. How can we tell that we need to skip the pm_runtime_put_sync for these devices? Would it be okay to call pm_runtime_put_sync immediately after the resume callback instead of after complete?
