This change is as per suggestion from Coccinelle: drivers/pci/controller/pcie-altera.c:717:2-9: line 717 is redundant because platform_get_irq() already prints an error Suggested-by: Bjorn Helgaas Signed-off-by: Krzysztof Wilczyński --- drivers/pci/controller/pcie-altera.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) diff --git a/drivers/pci/controller/pcie-altera.c b/drivers/pci/controller/pcie-altera.c index 24cb1c331058..f6d73d282230 100644 --- a/drivers/pci/controller/pcie-altera.c +++ b/drivers/pci/controller/pcie-altera.c @@ -713,10 +713,8 @@ static int altera_pcie_parse_dt(struct altera_pcie *pcie) /* setup IRQ */ pcie->irq = platform_get_irq(pdev, 0); - if (pcie->irq < 0) { - dev_err(dev, "failed to get IRQ: %d\n", pcie->irq); + if (pcie->irq < 0) return pcie->irq; - } irq_set_chained_handler_and_data(pcie->irq, altera_pcie_isr, pcie); return 0;
