commit: 062f380725376efab279956b5441071684c2a7ff [68/92] drm/amdgpu: Vega10 doorbell index initialization
config: x86_64-randconfig-x002-201847 (attached as .config)
compiler: gcc-7 (Debian 7.3.0-1) 7.3.0
reproduce:
        git checkout 062f380725376efab279956b5441071684c2a7ff
        # save the attached .config to linux build tree
        make ARCH=x86_64 

Note: the radeon-alex/drm-next-4.21 HEAD 2c486cc4c2774df684d8a43ca7a20670c67ccd76 builds fine.
      It only hurts bisectibility.
