From af2e2e35a23e4aeecfe4332a7140c81e0f09b7e3 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 29 Dec 2013 23:47:20 +0100 Subject: [PATCH] IB/mlx4: Fix error return code Set the return variable to an error code as done elsewhere in the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // Signed-off-by: Julia Lawall Signed-off-by: Roland Dreier --- drivers/infiniband/hw/mlx4/sysfs.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/drivers/infiniband/hw/mlx4/sysfs.c b/drivers/infiniband/hw/mlx4/sysfs.c index 97516eb363b7..db2ea31df832 100644 --- a/drivers/infiniband/hw/mlx4/sysfs.c +++ b/drivers/infiniband/hw/mlx4/sysfs.c @@ -582,8 +582,10 @@ static int add_port(struct mlx4_ib_dev *dev, int port_num, int slave) p->pkey_group.attrs = alloc_group_attrs(show_port_pkey, store_port_pkey, dev->dev->caps.pkey_table_len[port_num]); - if (!p->pkey_group.attrs) + if (!p->pkey_group.attrs) { + ret = -ENOMEM; goto err_alloc; + } ret = sysfs_create_group(&p->kobj, &p->pkey_group); if (ret) @@ -591,8 +593,10 @@ static int add_port(struct mlx4_ib_dev *dev, int port_num, int slave) p->gid_group.name = "gid_idx"; p->gid_group.attrs = alloc_group_attrs(show_port_gid_idx, NULL, 1); - if (!p->gid_group.attrs) + if (!p->gid_group.attrs) { + ret = -ENOMEM; goto err_free_pkey; + } ret = sysfs_create_group(&p->kobj, &p->gid_group); if (ret) -- 2.39.5
