With a second thought, 
__u8 serial[16] in drm_amdgpu_info_vbios is a bit redundant, sysfs serial_number already exposes it.

Is it fine to abandon it from drm_amdgpu_info_vbios struct? @Alex Deucher @Nieto, David M

Best regards,
Jiawei

Please make sure this keeps proper 64 bit alignment in the structure.
