From 946a88df76a2c5a9f4087fb41efd9d2763872302 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 14 Aug 2013 11:11:10 +0200 Subject: tegra: simplify use of devm_ioremap_resource 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/) // @@ 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); // Signed-off-by: Julia Lawall Signed-off-by: Stephen Warren --- drivers/iommu/tegra-smmu.c | 2 -- 1 file changed, 2 deletions(-) (limited to 'drivers/iommu') diff --git a/drivers/iommu/tegra-smmu.c b/drivers/iommu/tegra-smmu.c index f6f120e25409..e0665603afd9 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]); -- cgit v1.2.3
