[B.A.T.M.A.N.] [PATCH 09/20] batman-adv: Prefix bat_sysfs local static functions with batadv_

From: Sven Eckelmann sven@narfation.org

All non-static symbols of batman-adv were prefixed with batadv_ to avoid collisions with other symbols of the kernel. Other symbols of batman-adv should use the same prefix to keep the naming scheme consistent.
