From: Sven Eckelmann sven@narfation.org
The BATMAN_ADV_DEBUGFS portion of batman-adv is marked as deprecated. Thus all required functionality should be available without it. The debug log was already modified to also output via the kernel tracing function but still retained its BATMAN_ADV_DEBUGFS functionality.
Separate the entry point for the debug log from the debugfs portions to make it possible to build with BATMAN_ADV_DEBUG and without BATMAN_ADV_DEBUGFS.
