Subject: [PATCH 2/4] backlight: ep93xx: remove unnecessary platform_set_drvdata()
Date: Fri, 03 May 2013 15:17:50 +0900 [thread overview]
Message-ID: <000c01ce47c5$f063e110$d12ba330$@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.
