From 201a95afaa324b23188eeec268f6bb0b4b70b710 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Fri, 27 Oct 2006 15:26:21 -0700 Subject: [PATCH] [APPLETALK]: Fix potential OOPS in atalk_sendmsg(). atrtr_find() can return NULL, so do not blindly dereference rt->dev before we check for rt being NULL.
