From 1f8f4559f8c5829348a010a9e0bbb423310060d1 Mon Sep 17 00:00:00 2001 From: Micah Gruber Date: Fri, 28 Sep 2007 22:42:11 -0700 Subject: Fix a potential NULL pointer dereference in uli526x_interrupt() in drivers/net/tulip/uli526x.c This patch fixes an apparent potential null dereference bug where we dereference dev before a null check. This patch simply remvoes the can't-happen test for a null pointer.
