nouveau: Fix crash when pci_ram_rom() returns a size of 0 From b15b244d6e6e20964bd4b85306722cb60c3c0809 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt <benh@kernel.crashing.org> Date: Mon, 2 Apr 2012 13:28:18 +1000 Subject: Under some circumstances, pci_map_rom() can return a valid mapping but a size of 0 (if it cannot find an image in the header). This causes nouveau to try to kmalloc() a 0 sized pointer and dereference it, which crashes.
