Subject: [patch 2/2] iommu/mediatek: checking for IS_ERR() instead of NULL
Date: Wed, 2 Mar 2016 13:10:27 +0300 [thread overview]
Message-ID: <20160302101027.GG5533@mwanda> (raw)
of_platform_device_create() returns NULL on error, it never returns
error pointers.
Fixes: 0df4fabe208d ('iommu/mediatek: Add mt8173 IOMMU driver')
