Is this required? Are the harvesting fuses incorrect? If the blocks are harvested, we should bail out of the blocks properly during init. Also, please make this more explicit if we still need it. E.g.,
The harvest fuse is indeed disabling UVD and VCE, as it's a mining card.
Then any command to UVD/VCE causing NULL pointer issue, like amdgpu_test.
AFAIW, windows also disable UVD and VCE in initialization.
if ((adev->pdev->device == 0x67df) &&

amdgpu_device_ip_block_add(adev, &uvd_v6_3_ip_block);
amdgpu_device_ip_block_add(adev, &vce_v3_4_ip_block);
}
OK, will explicit the process.

That way if we re-arrange the order later, it will be easier to track.
