I think I found a workaround.

This error is caused by 

dtc -O dtb -o /tmp/dtbo -@ "$DTSO_FILE"
cat /tmp/dtbo > /sys/kernel/config/device-tree/overlays/default/dtbo

Piping the content of the dtbo seems not to work anymore.

The solution is to pipe the name of the dtbo file to the path argument of device-tree overlay. 

dtc -O dtb -o /lib/firmware/dtbo -@ "$DTSO_FILE"
echo dtbo > /sys/kernel/config/device-tree/overlays/default/path
