I really do not think this has any business being exported at all. kfd_queue_work is not something that should be done in a driver. Something like this belongs into the workqueue core, not in an underdocumented helper in a random driver. Drm guys: once again, please please work with the maintainers instead of just making up random stuff in the drivers.
