From 423595e89ddf9b657812a33932a5e2ad1bb9dd54 Mon Sep 17 00:00:00 2001 From: Amitoj Kaur Chawla Date: Mon, 1 Aug 2016 11:48:38 +0530 Subject: [PATCH] iommu/exynos: Fix error handling for of_platform_device_create of_platform_device_create returns NULL on error so an IS_ERR test is incorrect here and a NULL check is required. The Coccinelle semantic patch used to make this change is as follows: @@ expression e; @@ e = of_platform_device_create(...); if( - IS_ERR(e) + !e ) { <+... return - PTR_ERR(e) + -ENODEV ; ...+> } Signed-off-by: Amitoj Kaur Chawla Signed-off-by: Joerg Roedel --- drivers/iommu/exynos-iommu.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/iommu/exynos-iommu.c b/drivers/iommu/exynos-iommu.c index 33dcc29ec200..30808e91b775 100644 --- a/drivers/iommu/exynos-iommu.c +++ b/drivers/iommu/exynos-iommu.c @@ -1345,8 +1345,8 @@ static int __init exynos_iommu_of_setup(struct device_node *np) exynos_iommu_init(); pdev = of_platform_device_create(np, NULL, platform_bus_type.dev_root); - if (IS_ERR(pdev)) - return PTR_ERR(pdev); + if (!pdev) + return -ENODEV; /* * use the first registered sysmmu device for performing -- 2.39.5
