commit 1ad46c99623b89a1aa2140e5e588e1a354f024f1 Author: Simon Wunderlich simon.wunderlich@s2003.tu-chemnitz.de Date: Thu Feb 28 12:08:47 2013 +0100

batman-adv: change compat code to remove sparse warning

The latest compat patch fixing rtnl ops compile errors from 2.6.32 ("batman-adv: add compat support for the new netlink ops") fixes the compilation, but leaves some sparse errors: batman-adv/soft-interface.c:573:10: warning: Initializer entry defined twice batman-adv/soft-interface.c:574:10: also defined here

This patch uses another approach by moving the initializers in a dummy struct instead. This also removes the sparse errors.
