From d451f62a7c567654f74018be9ab8da8089660d3b Mon Sep 17 00:00:00 2001 From: Jakob Bornecrantz Date: Fri, 28 May 2010 11:22:02 +0200 Subject: [PATCH] drm/vmwgfx: Don't use SVGA_REG_ENABLE in modesetting code. We should not use SVGA_REG_ENABLE anywhere but in the fifo setup code, since it controls whether the device is active.
