From 367dc6586d2d9c0c347b567f7efec57f59c376fd Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 1 Feb 2018 11:25:27 +0100 Subject: [PATCH] net: bridge: Fix uninitialized error in br_fdb_sync_static() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit With gcc-4.1.2.: net/bridge/br_fdb.c: In function ‘br_fdb_sync_static’: net/bridge/br_fdb.c:996: warning: ‘err’ may be used uninitialized in this function Indeed, if the list is empty, err will be uninitialized, and will be propagated up as the function return value. Fix this by preinitializing err to zero. Fixes: eb7935830d00b9e0 ("net: bridge: use rhashtable for fdbs") Signed-off-by: Geert Uytterhoeven Acked-by: Nikolay Aleksandrov Signed-off-by: David S.
