From: Peter Senna Tschudin <peter.senna@xxxxxxxxx> 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 <peter.senna@xxxxxxxxx> --- drivers/virtio/virtio_pci.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/virtio/virtio_pci.c b/drivers/virtio/virtio_pci.c index 42b2076..c33aea3 100644 --- a/drivers/virtio/virtio_pci.c +++ b/drivers/virtio/virtio_pci.c @@ -719,8 +719,10 @@ static int __devinit virtio_pci_probe(struct pci_dev *pci_dev, goto out_enable_device; vp_dev->ioaddr = pci_iomap(pci_dev, 0, 0); - if (vp_dev->ioaddr == NULL) + if (vp_dev->ioaddr == NULL) { + err = -ENOMEM; goto out_req_regions; + } pci_set_drvdata(pci_dev, vp_dev); pci_set_master(pci_dev); -- 1.7.11.4 -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
