The following commit has been merged in the master branch:
commit 993a4a5f7cd3aef53be3953d11f86b2d3630ebb8
Author: Sven Eckelmann <sven(a)narfation.org>
Date: Sat Jul 7 21:50:18 2018 +0200
batman-adv: Convert batadv_dat_addr_t to proper type
The #define for batadv_dat_addr_t is doing nothing else than giving u16 a
new typename. But C already has the special keyword "typedef" which is also
better supported by kernel-doc.
