If the driver doesn't do anything just remove the code.

"Class D over current".  The verbosity is making the line over long and
the phrasing is a bit unclear (and makes it seem less critical than it
really is).  These should probably be dev_crit() or somthing too, over
current and similar events on a speaker output are generally extremely
serious.
