From 92656d707e961c88b6f931038c7dc41790a52e1e Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Tue, 12 Apr 2011 13:32:13 -0400 Subject: [PATCH] drm/radeon/kms: clean up gart dummy page handling As per Konrad's original patch, the dummy page used by the gart code and allocated in radeon_gart_init() was not freed properly in radeon_gart_fini(). At the same time r6xx and newer allocated and freed the dummy page on their own. So to do Konrad's patch one better, just remove the allocation and freeing of the dummy page in the r6xx, 7xx, evergreen, and ni code and allocate and free in the gart_init/fini() functions for all asics.
