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. Signed-off-by: NMa Ling <ling.ma@intel.com> Signed-off-by: NDave Airlie <airlied@redhat.com>
