Subject: [patch] iommu/exynos: checking for IS_ERR() instead of NULL
Date: Wed, 2 Mar 2016 13:10:47 +0300 [thread overview]
Message-ID: <20160302101047.GH5533@mwanda> (raw)
of_platform_device_create() returns NULL on error, it never returns
error pointers.
Fixes: 8ed55c812fa8 ('iommu/exynos: Init from dt-specific callback instead of initcall')
