[PATCH 1/2] dma: at_hdmac: remove unnecessary platform_set_drvdata()

From: Jingoo Han
Date: Sun May 05 2013 - 23:53:39 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.
