Subject: [PATCH 32/36] net: wireless: ath: remove unnecessary platform_set_drvdata()

From: Jingoo Han <[email-masked]>
Date: Tue, 07 May 2013 14:01:20 +0900

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.
