For anyone who are failing builds with #FreeBSD #ports graphics/nvidia-drm-{510|515|61|66|latest}-kmod{-devel} on 13.5-RELEASE, 14.3-RELEASE or stable/13:

Does the patch at review D56214 fix your issue?
https://reviews.freebsd.org/D56214

Note that the newer patch at Bug 294096 is technically the same one.
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=294096

If it doesn't work, older patch at Bug 294096 should work (but overkill for unaffected 15.4-RELEASE, stable/15 and main).
