Greg,

This error occurs because the patch "libfdt: Add fdt_path_offset_namelen()"
has not been upstreamed yet by the devicetree maintainers.

Please back out commits 5a95cfdfaf5c ("of: earlycon: Fix 'stdout-path' with ':' path terminator")
through 865f9cc509db ("of: earlycon: Log more helpful message if earlycon not found")
from tty-testing.

I'll just resend the series when the situation with the missing
commit has been sorted.

Regards,
Peter Hurley
