From: Peter Senna Tschudin <[email protected]> Convert a nonnegative error return code to a negative one, as returned elsewhere in the function.
A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Peter Senna Tschudin <[email protected]> --- drivers/net/ethernet/sis/sis900.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/net/ethernet/sis/sis900.c b/drivers/net/ethernet/sis/sis900.c index 203d9c6..fb9f6b3 100644 --- a/drivers/net/ethernet/sis/sis900.c +++ b/drivers/net/ethernet/sis/sis900.c @@ -478,8 +478,10 @@ static int __devinit sis900_probe(struct pci_dev *pci_dev, /* IO region. */ ioaddr = pci_iomap(pci_dev, 0, 0); - if (!ioaddr) + if (!ioaddr) { + ret = -ENOMEM; goto err_out_cleardev; + } sis_priv = netdev_priv(net_dev); sis_priv->ioaddr = ioaddr; -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
