This change is as per suggestion from Coccinelle: drivers/pci/controller/pcie-tango.c:277:2-9: line 277 is redundant because platform_get_irq() already prints an error Suggested-by: Bjorn Helgaas Signed-off-by: Krzysztof Wilczyński --- drivers/pci/controller/pcie-tango.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) diff --git a/drivers/pci/controller/pcie-tango.c b/drivers/pci/controller/pcie-tango.c index 8f640c70f936..d093a8ce4bb1 100644 --- a/drivers/pci/controller/pcie-tango.c +++ b/drivers/pci/controller/pcie-tango.c @@ -273,10 +273,8 @@ static int tango_pcie_probe(struct platform_device *pdev) writel_relaxed(0, pcie->base + SMP8759_ENABLE + offset); virq = platform_get_irq(pdev, 1); - if (virq < 0) { - dev_err(dev, "Failed to map IRQ\n"); + if (virq < 0) return virq; - } irq_dom = irq_domain_create_linear(fwnode, MSI_MAX, &dom_ops, pcie); if (!irq_dom) {
