Sometimes when trying to enable some feature, we have to define some values with educated guesses, but we mark those values as TBD, which means "To Be Determined". However, the correct way to approach it is by loading that information from the firmware. Anyway, some of the values that we were experimenting with caused this issue: ERROR: modpost: "__muldf3" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined! This commit fixes this issue by removing the division by two since it is harmless in this case.
