Driver core: Fix cleanup when failing device_add().
Driver core: Fix cleanup when failing device_add().
- Don't call cleanup_device_parent() if we didn't call setup_parent().
- dev->kobj.parent may be NULL when cleanup_device_parent() is called,
so we need to handle glue_dir == NULL in cleanup_glue_dir().
