Date
4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit b4201cc4fc6e1c57d6d306b1f787865043d60129 ]

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.
