netconsole: avoid null pointer dereference at show_local_mac() This patch avoids a null pointer dereference when we read local_mac for netconsole in configfs and shows default local mac address value. A null pointer dereference occurs when we call show_local_mac() via local_mac entry in configfs before we setup the content of netpoll using netpoll_setup().
