The following commit has been merged in the master branch:
commit dc06338df9a8443dcff6c7be03ab792ea682d9ab
Author: Sven Eckelmann <sven at narfation.org>
Date:   Thu Apr 19 21:01:08 2018 +0200

    batman-adv: Remove unused dentry without DEBUGFS
    
    The debug_dir variable in the main structures is only accessed when
    CONFIG_BATMAN_ADV_DEBUGFS is enabled. It can be dropped to potentially save
    some bytes of memory.
