I looked through all the users of this and couldn't fine one that actually
benefits from it. I'd say better drop this patch entirely and open-code
the contents in the callers. That will help readability since the dma
API is well understood by many people.
Generally speaking, try not to wrap Linux interfaces into driver specific
helper functions.
