thanks a lot for this notification.

I'm surprised that overlay build at all when I built it yesterday. But yeah, the dtbs_install target really broke with that change.

I've amended the commit now [0], to change dtso to dtbo and ran the dtbs_install target sucessfully with that change.

So on the next linux-next creation, this should hopefully be gone.
