From 43bbfa109a44c217889a72041060f570a2f92ffe Mon Sep 17 00:00:00 2001
From: Jingoo Han <jg1.han@samsung.com>

Subject: mmc: remove unnecessary platform_set_drvdata()
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.
