Subject: [PATCH] iommu: remove unnecessary platform_set_drvdata()
Date: Thu, 22 Aug 2013 10:53:01 +0900	[thread overview]
Message-ID: <001501ce9eda$5660b2c0$03221840$%han@samsung.com> (raw)

The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.
