From 7b1bbe883b3ed962ca2be4daf321f318f5091340 Mon Sep 17 00:00:00 2001 From: Alex Deucher <alexander.deucher@amd.com> Date: Wed, 12 Mar 2014 15:15:58 -0400 Subject: [PATCH] drm/radeon/cik: properly set sdma ring status on disable When we disable the rings, set the status properly. If not other code pathes may try and use the rings which are not functional at this point.
