Description David Binderman 2014-09-08 07:04:32 UTC 
net/batman-adv/gateway_client.c:813:31: warning: logical not is only applied to the left hand side of comparison [-Wlogical-not-parentheses]

    gw_node = batadv_gw_node_get(bat_priv, orig_dst_node);
    if (!gw_node->bandwidth_down == 0)
        goto out;

Function batadv_gw_node_get can return NULL, so there's
a missing sanity check there and maybe the if condition
can be reworked for clarity.
