From: Jeff Mahoney Date: Mon, 4 Apr 2016 18:15:23 +0000 (-0400) Subject: mac80211: fix "warning: ‘target_metric’ may be used uninitialized" X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b4201cc4fc6e1c57d6d306b1f787865043d60129;p=linux-beck.git 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.
