This change is as per suggestion from Coccinelle: drivers/pci/controller/pcie-rockchip-host.c:553:2-9: line 553 is redundant because platform_get_irq() already prints an error drivers/pci/controller/pcie-rockchip-host.c:566:2-9: line 566 is redundant because platform_get_irq() already prints an error drivers/pci/controller/pcie-rockchip-host.c:576:2-9: line 576 is redundant because platform_get_irq() already prints an error Suggested-by: Bjorn Helgaas Signed-off-by: Krzysztof Wilczyński --- drivers/pci/controller/pcie-rockchip-host.c | 12 +++--------- 1 file changed, 3 insertions(+), 9 deletions(-) diff --git a/drivers/pci/controller/pcie-rockchip-host.c b/drivers/pci/controller/pcie-rockchip-host.c index 94af6f5828a3..eebe05ab354f 100644 --- a/drivers/pci/controller/pcie-rockchip-host.c +++ b/drivers/pci/controller/pcie-rockchip-host.c @@ -549,10 +549,8 @@ static int rockchip_pcie_setup_irq(struct rockchip_pcie *rockchip) struct platform_device *pdev = to_platform_device(dev); irq = platform_get_irq_byname(pdev, "sys"); - if (irq < 0) { - dev_err(dev, "missing sys IRQ resource\n"); + if (irq < 0) return irq; - } err = devm_request_irq(dev, irq, rockchip_pcie_subsys_irq_handler, IRQF_SHARED, "pcie-sys", rockchip); @@ -562,20 +560,16 @@ static int rockchip_pcie_setup_irq(struct rockchip_pcie *rockchip) } irq = platform_get_irq_byname(pdev, "legacy"); - if (irq < 0) { - dev_err(dev, "missing legacy IRQ resource\n"); + if (irq < 0) return irq; - } irq_set_chained_handler_and_data(irq, rockchip_pcie_legacy_int_handler, rockchip); irq = platform_get_irq_byname(pdev, "client"); - if (irq < 0) { - dev_err(dev, "missing client IRQ resource\n"); + if (irq < 0) return irq; - } err = devm_request_irq(dev, irq, rockchip_pcie_client_irq_handler, IRQF_SHARED, "pcie-client", rockchip); -- 2.27.0
