[PATCH v5 2/5] ARM: sa1111: ensure no negative value gets returned on positive match

From: Marek Szyprowski
Date: Wed Dec 23 2015 - 06:00:55 EST


This patch ensures that existing bus match callbacks don't return
negative values (which might be interpreted as potential errors in the
future) in case of positive match.
