From 4a4bfdcd29572864a561f64a09af9ff444f3cd41 Mon Sep 17 00:00:00 2001 From: Peter Senna Tschudin Date: Wed, 3 Oct 2012 18:17:54 +0200 Subject: [PATCH] can: peak_pci: fix error return code 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/) // ( 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: Peter Senna Tschudin Signed-off-by: Marc Kleine-Budde --- drivers/net/can/sja1000/peak_pci.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/net/can/sja1000/peak_pci.c b/drivers/net/can/sja1000/peak_pci.c index f0a12962f7b6..f5b82aeb2540 100644 --- a/drivers/net/can/sja1000/peak_pci.c +++ b/drivers/net/can/sja1000/peak_pci.c @@ -583,12 +583,14 @@ static int __devinit peak_pci_probe(struct pci_dev *pdev, cfg_base = pci_iomap(pdev, 0, PEAK_PCI_CFG_SIZE); if (!cfg_base) { dev_err(&pdev->dev, "failed to map PCI resource #0\n"); + err = -ENOMEM; goto failure_release_regions; } reg_base = pci_iomap(pdev, 1, PEAK_PCI_CHAN_SIZE * channels); if (!reg_base) { dev_err(&pdev->dev, "failed to map PCI resource #1\n"); + err = -ENOMEM; goto failure_unmap_cfg_base; }
