From: Julia Lawall <julia.law...@lip6.fr> Remove unneeded error handling on the result of a call to platform_get_resource when the value is passed to devm_ioremap_resource.
A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression pdev,res,n,e,e1; expression ret != 0; identifier l; @@ - res = platform_get_resource(pdev, IORESOURCE_MEM, n); ... when != res - if (res == NULL) { ... \(goto l;\|return ret;\) } ... when != res + res = platform_get_resource(pdev, IORESOURCE_MEM, n); e = devm_ioremap_resource(e1, res); // </smpl> Signed-off-by: Julia Lawall <julia.law...@lip6.fr> --- drivers/iommu/tegra-smmu.c | 2 -- drivers/memory/tegra20-mc.c | 2 -- drivers/memory/tegra30-mc.c | 2 -- 3 files changed, 6 deletions(-) diff --git a/drivers/iommu/tegra-smmu.c b/drivers/iommu/tegra-smmu.c index f6f120e..e066560 100644 --- a/drivers/iommu/tegra-smmu.c +++ b/drivers/iommu/tegra-smmu.c @@ -1177,8 +1177,6 @@ static int tegra_smmu_probe(struct platform_device *pdev) struct resource *res; res = platform_get_resource(pdev, IORESOURCE_MEM, i); - if (!res) - return -ENODEV; smmu->regs[i] = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(smmu->regs[i])) return PTR_ERR(smmu->regs[i]); diff --git a/drivers/memory/tegra20-mc.c b/drivers/memory/tegra20-mc.c index 0548eea..7cd82b8 100644 --- a/drivers/memory/tegra20-mc.c +++ b/drivers/memory/tegra20-mc.c @@ -218,8 +218,6 @@ static int tegra20_mc_probe(struct platform_device *pdev) struct resource *res; res = platform_get_resource(pdev, IORESOURCE_MEM, i); - if (!res) - return -ENODEV; mc->regs[i] = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(mc->regs[i])) return PTR_ERR(mc->regs[i]); diff --git a/drivers/memory/tegra30-mc.c b/drivers/memory/tegra30-mc.c index 58d2979..ef79345 100644 --- a/drivers/memory/tegra30-mc.c +++ b/drivers/memory/tegra30-mc.c @@ -340,8 +340,6 @@ static int tegra30_mc_probe(struct platform_device *pdev) struct resource *res; res = platform_get_resource(pdev, IORESOURCE_MEM, i); - if (!res) - return -ENODEV; mc->regs[i] = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(mc->regs[i])) return PTR_ERR(mc->regs[i]); -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
