From 36c6df5062568f0b923930b63e2e477cb3a391bd Mon Sep 17 00:00:00 2001 From: Jingoo Han <jg1.han@samsung.com> Date: Mon, 6 May 2013 12:53:33 +0900 Subject: [PATCH] dma: at_hdmac: 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.
