This broke the drm-tip build:

../drivers/gpu/drm/amd/amdgpu/amdgpu_device.c: In function ‘amdgpu_device_parse_gpu_info_fw’:
../drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:2668:31: error: ‘struct amdgpu_mman’ has no member named ‘discovery_bin’
 2668 |                 if (adev->mman.discovery_bin)
      |                               ^

and it's going to need a fixup.

BR,
Jani.
