Subject: [PATCH] vxlan: Refactor vxlan_udp_encap_recv() to kill compiler warning
Date: Fri, 4 Sep 2015 12:49:32 +0200 [thread overview]
Message-ID: <1441363772-20850-1-git-send-email-geert@linux-m68k.org> (raw)
drivers/net/vxlan.c: In function ‘vxlan_udp_encap_recv’:
drivers/net/vxlan.c:1226: warning: ‘info’ may be used uninitialized in this function
While this warning is a false positive, it can be killed easily by
getting rid of the pointer intermediary and referring directly to the
ip_tunnel_info structure.
