[PATCH 4/8] mfd: twl4030-madc: remove unnecessaryplatform_set_drvdata()

From: Jingoo Han
Date: Mon May 06 2013 - 00:08:14 EST


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.
