I can do it as a follow-up patch if there is no other reason to spin,
but I realized that I forgot to add:
.flags = DRM_MODE_FLAG_PHSYNC | DRM_MODE_FLAG_NVSYNC,
...to both the 40 and 60 Hz modes to make it match what's in the EDID.
I'm also OK w/ it getting added by a maintainer when this lands if
that makes sense.
