The error check on err is redundant as it is being checked
previously each time it has been updated. Remove this redundant
check.

Actually that code can be reduced further, I'll follow up with a patch later.

..and one more thing, in net/bridge/br_netlink_tunnel.c,
__get_num_vlan_tunnel_infos, are the args to vlan_tunnel_id_isrange()
the wrong way around? I'm not 100% sure, but I'd thought I'd flag it up.
if (v_start) {
if ((v_end->vid - v->vid) > 0 &&
vlan_tunnel_id_isrange(v_end, v) > 0)
num_tinfos += 2;
else
num_tinfos += 1;
}
