If CONFIG_DEBUG_FS is disabled debugfs_create_file returns -ENODEV instead of zero. Since the return value is stored and used at shutdown to remove existing entries an OOPS may be triggered. Add a check of the debugfs_create_file return value and in case of an error set the entry to NULL so it will be ignored at shutdown. Signed-off-by:
