From a1d6086739c5b8f23a48e02e62b0e495321a2122 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 15 Mar 2011 10:07:37 +0300 Subject: [PATCH] asus-wmi: potential NULL dereference in show_call() In the earlier check we assumed that "obj" could be NULL. I looked at some of the other places that call evaluate_object() and they check for NULL as well.
