From 1ef997dca4ebeaca56783430de848a8d207ec879 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Mon, 6 May 2013 13:40:21 +0900 Subject: [PATCH] hwrng: tx4939 - 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.
