From f9274562026558ab54a29331cf13e9ebec8cc890 Mon Sep 17 00:00:00 2001 From: Jerome Glisse Date: Wed, 17 Mar 2010 14:44:29 +0000 Subject: drm/radeon/kms: avoid possible oops (call gart_fini before gart_disable) radeon_gart_fini might call GART unbind callback function which might try to access GART table but if gart_disable is call first the GART table will be unmapped so any access to it will oops.
