If you're doing something like this you should remove the code rather
than if 0 it out, or at least insert a comment explaining why the code
is sitting around.  Though I'm a bit concerned that if something has
actually tried to set up circular DMA it might get upset if that's
ignored (not that I've looked in detail).
