The patch included in bug #1038014 does not full resolve this issue.
I still got the following build error:
/var/lib/dkms/nvidia-legacy-390xx/390.157/build/nvidia-drm/nvidia-drm-fb.c:

The included patch solves both #1038014
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1038014> and the
error above.
