From 8ba7acf376e39ff2b987bc8fb71eb599023af314 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Sun, 30 Sep 2012 17:07:19 +0200 Subject: [PATCH] mac80211: remove unimplemented mesh vendor sync There's no vendor-specific mesh sync implemented and there don't need to be dummy handlers that only print messages, so remove that code. While at it, also constify the mesh sync ops.
