From fa8005a5d241227c47121b94a56b3a9bb8dd0610 Mon Sep 17 00:00:00 2001 From: Marcelo Ricardo Leitner Date: Mon, 23 Mar 2015 16:23:12 -0300 Subject: [PATCH] vxlan: simplify if clause in dev_close Dan Carpenter's static checker warned that in vxlan_stop we are checking if 'vs' can be NULL while later we simply derreference it. As after commit 9538361f2727 ("vxlan: Move socket initialization to within rtnl scope") 'vs' just cannot be NULL in vxlan_stop() anymore, as the interface won't go up if the socket initialization fails. So we are good to just remove the check and make it consistent. Reported-by: Dan Carpenter Signed-off-by: Marcelo Ricardo Leitner Signed-off-by: David S.
