3.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Deucher <alexander.deuc...@amd.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.
