Is anyone looking into fixing this:

drivers/gpu/drm/amd/amdgpu/amdgpu_gtt_mgr.c: In function ʽamdgpu_gtt_mgr_recoverʼ:
drivers/gpu/drm/amd/amdgpu/amdgpu_gtt_mgr.c:200:31: error: ʽstruct ttm_range_mgr_nodeʼ has no member named ʽtboʼ
   amdgpu_ttm_recover_gart(node->tbo);
                               ^~
make[4]: *** [scripts/Makefile.build:288: drivers/gpu/drm/amd/amdgpu/amdgpu_gtt_mgr.o] Error 1

Thanks.
