drivers/net/fs_enet: remove null pointer dereference
The following code appears in the function fs_init_instance in the file drivers/net/fs_enet/fs_enet-main.c. if (fep->ops == NULL) { printk(KERN_ERR DRV_MODULE_NAME ": %s No matching ops found (%d).\n", ndev->name, fpi->fs_no); err = -EINVAL; goto err; } This code implies that at the point of err, fep->ops can be NULL, so an extra test is needed before dereferencing this value. This problem was found using the following semantic match (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E, E1; identifier f; statement S1,S2,S3; @@ * if (E == NULL) { ... when != if (E == NULL) S1 else S2 when != E = E1 * E->f ... when any return ...; } else S3 // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
