mac80211: fix "warning: ‘target_metric’ may be used uninitialized"
This fixes: net/mac80211/mesh_hwmp.c:603:26: warning: ‘target_metric’ may be used uninitialized in this function target_metric is only consumed when reply = true so no bug exists here, but not all versions of gcc realize it. Initialize to 0 to remove the warning. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
