Subject: drm/radeon/cik: properly set sdma ring status on disable
From: Alex Deucher <[email protected]>
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.
