From 87f0a427547d8552f87bfb19baa3d66d528aa761 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Tue, 7 May 2013 14:32:11 +0900 Subject: misc: arm-charlcd: 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.
