This change is as per suggestion from Coccinelle: drivers/pci/controller/pcie-xilinx-nwl.c:732:2-9: line 732 is redundant because platform_get_irq() already prints an error drivers/pci/controller/pcie-xilinx-nwl.c:589:2-9: line 589 is redundant because platform_get_irq() already prints an error drivers/pci/controller/pcie-xilinx-nwl.c:600:2-9: line 600 is redundant because platform_get_irq() already prints an error drivers/pci/controller/pcie-xilinx-nwl.c:801:2-9: line 801 is redundant because platform_get_irq() already prints an error Suggested-by: Bjorn Helgaas Signed-off-by: Krzysztof Wilczyński --- drivers/pci/controller/pcie-xilinx-nwl.c | 11 ++--------- 1 file changed, 2 insertions(+), 9 deletions(-) diff --git a/drivers/pci/controller/pcie-xilinx-nwl.c b/drivers/pci/controller/pcie-xilinx-nwl.c index 9bd1427f2fd6..55489b728484 100644 --- a/drivers/pci/controller/pcie-xilinx-nwl.c +++ b/drivers/pci/controller/pcie-xilinx-nwl.c @@ -586,7 +586,6 @@ static int nwl_pcie_enable_msi(struct nwl_pcie *pcie) /* Get msi_1 IRQ number */ msi->irq_msi1 = platform_get_irq_byname(pdev, "msi1"); if (msi->irq_msi1 < 0) { - dev_err(dev, "failed to get IRQ#%d\n", msi->irq_msi1); ret = -EINVAL; goto err; } @@ -597,7 +596,6 @@ static int nwl_pcie_enable_msi(struct nwl_pcie *pcie) /* Get msi_0 IRQ number */ msi->irq_msi0 = platform_get_irq_byname(pdev, "msi0"); if (msi->irq_msi0 < 0) { - dev_err(dev, "failed to get IRQ#%d\n", msi->irq_msi0); ret = -EINVAL; goto err; } @@ -728,11 +726,8 @@ static int nwl_pcie_bridge_init(struct nwl_pcie *pcie) /* Get misc IRQ number */ pcie->irq_misc = platform_get_irq_byname(pdev, "misc"); - if (pcie->irq_misc < 0) { - dev_err(dev, "failed to get misc IRQ %d\n", - pcie->irq_misc); + if (pcie->irq_misc < 0) return -EINVAL; - } err = devm_request_irq(dev, pcie->irq_misc, nwl_pcie_misc_handler, IRQF_SHARED, @@ -797,10 +792,8 @@ static int nwl_pcie_parse_dt(struct nwl_pcie *pcie, /* Get intx IRQ number */ pcie->irq_intx = platform_get_irq_byname(pdev, "intx"); - if (pcie->irq_intx < 0) { - dev_err(dev, "failed to get intx IRQ %d\n", pcie->irq_intx); + if (pcie->irq_intx < 0) return pcie->irq_intx; - } irq_set_chained_handler_and_data(pcie->irq_intx, nwl_pcie_leg_handler, pcie); -- 2.27.0
