-       if (unlikely(smu->smu_debug_mask & SMU_DEBUG_HALT_ON_ERROR) &&
+       if (unlikely(adev->smu_debug_mask & SMU_DEBUG_HALT_ON_ERROR) &&
            res && (res != -ETIME)) {
                amdgpu_device_halt(smu->adev);

[Guchun] As we have set an 'adev' variable, we can replace 'smu->adev' with 
'adev' in each function directly.

Regards,
Guchun

Subject: [PATCH] drm/amdgpu: move smu_debug_mask to a more proper place

As the smu_context will be invisible from outside(of power). Also, the 
smu_debug_mask can be shared around all power code instead of some specific 
framework(swSMU) only.
