That change makes no sense to me - the original code was

	if (error)
		DPRINTF((....));

and even if DPRINTF() could produce nothing, the result would be

	if (error)
		;

which is perfectly good C (useless, but acceptable).  Adding { } around
the ';' changes nothing.

But in any case, apb changed it yesterday, so DPRINTF() never produces
nothing (personally I'm not sure that should have been needed, but that's
beside the point).

What was the error that resulted in the addition of the {} ?
