[PATCH -next] iommu/exynos: Fix return value check in exynos_iommu_of_setup()

Hi,

just a question,

quoted

 	pdev = of_platform_device_create(np, NULL, platform_bus_type.dev_root);
-	if (IS_ERR(pdev))
-		return PTR_ERR(pdev);
+	if (!pdev)
+		return -ENOMEM;
 
 	/*
 	 * use the first registered sysmmu device for performing

is ENOMEM the right return value? of_platform_device_create()
doesn't fail only in case of malloc failure.

Shouldn't it be ENODEV instead, which might also mean with some
imagination that there is no memory available for that device?

Thanks,
Andi
