From: Julia Lawall <julia@xxxxxxx> The initializations of both fcoe_nport_scsi_transport and fcoe_vport_scsi_transport can fail, so test both of them. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier x,y,f!={PTR_ERR,ERR_PTR,ERR_CAST}; statement S; @@ x = f(...); ( if (\(x == NULL\|IS_ERR(x)\)) S | *if (\(y == NULL\|IS_ERR(y)\)) { ... when != x return ...; } ) // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/scsi/fcoe/fcoe.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/scsi/fcoe/fcoe.c b/drivers/scsi/fcoe/fcoe.c index ba710e3..921b636 100644 --- a/drivers/scsi/fcoe/fcoe.c +++ b/drivers/scsi/fcoe/fcoe.c @@ -1096,7 +1096,7 @@ static int __init fcoe_if_init(void) fcoe_vport_scsi_transport = fc_attach_transport(&fcoe_vport_fc_functions); - if (!fcoe_nport_scsi_transport) { + if (!fcoe_nport_scsi_transport || !fcoe_vport_scsi_transport) { printk(KERN_ERR "fcoe: Failed to attach to the FC transport\n"); return -ENODEV; } -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
