From 738e1e694bf6d9e965ba0ce2667a1bec5780a172 Mon Sep 17 00:00:00 2001 From: Petr Vandrovec Date: Sun, 12 Oct 2008 20:58:29 -0700 Subject: [PATCH] r8169: NULL pointer dereference on r8169 load mmio_addr in r8169 needs to be initialized before use Maybe that all tp-> initialization should be moved before rtl_init_mac_address call, but this is enough to get rid of crash in rtl_rar_set due to mmio_addr being uninitialized.
