Subject: ovs-brcompatd: Use error instead of pointer in handle_fdb_query_cmd().
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4869f1b170c1741fbc8f81123d0fe5fc1ba3a282;p=openvswitch

ovs-brcompatd: Use error instead of pointer in handle_fdb_query_cmd().

It is safe to use either value here but as long as we are saving the
error value we might as well use it.

Found by Clang (http://clang-analyzer.llvm.org/).
