flush_scheduled_work() is deprecated and will be removed. Because kcapi uses fire-and-forget type works, it's impossible to flush each work explicitly. Create and use a dedicated workqueue instead. Please note that with recent workqueue changes, each workqueue doesn't reserve a lot of resources and using it as a flush domain is fine.
