From 6950a235b86cf4e73d2b8e5476e7d0eb8f61af63 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 21 Jan 2013 13:02:58 +0000 Subject: IB/mlx4: Adjust duplicate test Delete successive tests to the same location. The code tested the result of a previous allocation, that itself was already tested. It is changed to test the result of the most recent allocation. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @s exists@ local idexpression y; expression x,e; @@ *if ( \(x == NULL\|IS_ERR(x)\|y != 0\) ) { ... when forall return ...; } ... when != \(y = e\|y += e\|y -= e\|y |= e\|y &= e\|y++\|y--\|&y\) when != \(XT_GETPAGE(...,y)\|WMI_CMD_BUF(...)\) *if ( \(x == NULL\|IS_ERR(x)\|y != 0\) ) { ... when forall return ...; } // Signed-off-by: Julia Lawall Signed-off-by: Roland Dreier --- drivers/infiniband/hw/mlx4/sysfs.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/infiniband') diff --git a/drivers/infiniband/hw/mlx4/sysfs.c b/drivers/infiniband/hw/mlx4/sysfs.c index 5b2a01dfb90..97516eb363b 100644 --- a/drivers/infiniband/hw/mlx4/sysfs.c +++ b/drivers/infiniband/hw/mlx4/sysfs.c @@ -732,7 +732,7 @@ int mlx4_ib_device_register_sysfs(struct mlx4_ib_dev *dev) dev->ports_parent = kobject_create_and_add("ports", kobject_get(dev->iov_parent)); - if (!dev->iov_parent) { + if (!dev->ports_parent) { ret = -ENOMEM; goto err_ports; } -- cgit v1.2.3-18-g5258
