[PATCH v5 RESEND 1/5] drivers: nvdimm: ensure no negative value gets returned on positive match
From: Marek Szyprowski
Date: Wed Feb 10 2016 - 05:48:08 EST
From: Dan Williams <dan.j.williams@xxxxxxxxx>
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.
