From 45dcd36e1ebbb3c085bdd157bffaf9276ffd8c46 Mon Sep 17 00:00:00 2001 From: Stefano Stabellini Date: Fri, 3 Jun 2011 16:56:54 +0100 Subject: [PATCH] cirrus_vga: reset lfb_addr after a pci config write if the BAR is unmapped If the cirrus_vga PCI BAR is unmapped than we should not only reset map_addr but also lfb_addr, otherwise we'll keep trying to map the old lfb_addr in map_linear_vram.
