This change is as per suggestion from Coccinelle: drivers/pci/controller/pci-v3-semi.c:781:2-9: line 781 is redundant because platform_get_irq() already prints an error Suggested-by: Bjorn Helgaas Signed-off-by: Krzysztof Wilczyński --- drivers/pci/controller/pci-v3-semi.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) diff --git a/drivers/pci/controller/pci-v3-semi.c b/drivers/pci/controller/pci-v3-semi.c index 3681e5af3878..2a19f2a98945 100644 --- a/drivers/pci/controller/pci-v3-semi.c +++ b/drivers/pci/controller/pci-v3-semi.c @@ -777,10 +777,9 @@ static int v3_pci_probe(struct platform_device *pdev) /* Get and request error IRQ resource */ irq = platform_get_irq(pdev, 0); - if (irq < 0) { - dev_err(dev, "unable to obtain PCIv3 error IRQ\n"); + if (irq < 0) return irq; - } + ret = devm_request_irq(dev, irq, v3_irq, 0, "PCIv3 error", v3); if (ret < 0) {
