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.,
if ((adev->pdev->device == 0x67df) &&
(adev->pdev->revision == 0xf7)) {
/* Some polaris12 variants don't support UVD/VCE */
} else {
amdgpu_device_ip_block_add(adev, &uvd_v6_3_ip_block);
amdgpu_device_ip_block_add(adev, &vce_v3_4_ip_block);
}
That way if we re-arrange the order later, it will be easier to track.
