From 77d26dc9b9805f322f5a1f6e559b18ad66205bd9 Mon Sep 17 00:00:00 2001 From: Ma Ling Date: Thu, 16 Apr 2009 17:51:25 +0800 Subject: [PATCH] drm: clean dirty memory after device release In current code we register/unregister connector object by drm_sysfs_connector_add/remove function. However under some cases, we need to dynamically register or unregister device multiple times, so we have to go through register -> unregister ->register routine. Because after device_unregister function our memory is dirty, we need to do clean operation in order to re-register the device, otherwise the system will crash. The patch intends to clean device after device release.
