Got this when compiling with Linux-5.10.81:

drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_device.c: In function
‘kgd2kfd_device_init’:
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_device.c:754:6: error: implicit
declaration of function ‘kgd2kfd_resume_iommu’; did you mean
‘kgd2kfd_resume_mm’? [-Werror=implicit-function-declaration]
  754 |  if (kgd2kfd_resume_iommu(kfd))
      |      ^~~~~~~~~~~~~~~~~~~~
      |      kgd2kfd_resume_mm
