From: Alex Deucher <alexander.deucher@xxxxxxx> This patch has been added to the 3.12 stable tree. If you have any objections, please let us know. =============== 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.
