Message-Id: <20140321000440.600346024@linuxfoundation.org> Date: Thu, 20 Mar 2014 17:04:28 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Alex Deucher <alexander.deucher@....com> Subject: [PATCH 3.13 105/149] drm/radeon/cik: properly set sdma ring status on disable 3.13-stable review patch. If anyone has any objections, please let me know. ------------------ From: Alex Deucher <alexander.deucher@....com> commit 7b1bbe883b3ed962ca2be4daf321f318f5091340 upstream. 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.
