drm/radeon: fix active_cu mask on SI and CIK after re-init (v3)
Need to initialize the mask to 0 on init, otherwise it keeps increasing. bug: https://bugzilla.kernel.org/show_bug.cgi?id=82581 v2: also fix cu count v3: split count fix into separate patch Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Michel Dänzer <michel.daenzer@amd.com> Cc: stable@vger.kernel.org
