Subject: [PATCH 4/4] hwrng: tx4939 - remove unnecessary platform_set_drvdata()
Date: Mon, 06 May 2013 13:40:21 +0900 [thread overview]
Message-ID: <004901ce4a13$d14b7360$73e25a20$@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.
