From dfd2a17809b787dea44eec76ab9f3de8b7fcb8d6 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Wed, 3 Jul 2013 15:06:37 -0700 Subject: [PATCH] rtc: rtc-stmp3xxx: remove unnecessary platform_set_drvdata() The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata = NULL when no driver is bound"). Thus, it is not needed to manually clear the device driver data to NULL.
