Subject: [PATCH 3/4] hwrng: timeriomem - remove unnecessary platform_set_drvdata()
Date: Mon, 06 May 2013 13:39:38 +0900	[thread overview]
Message-ID: <004801ce4a13$b7853ec0$268fbc40$@samsung.com> (raw)

The driver core clears the driver data to NULL after device_release
or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
(device-core: Ensure drvdata = NULL when no driver is bound).
Thus, it is not needed to manually clear the device driver data to NULL.
