commit db59ef4cdc3261322ea61686e714b571ef709484 ("of: unittest: Unit-tests for target root overlays.")

We found some OF unittests errors in kernel log, while the line marked
with + is new after this commit.  This is intended? Or should be fixed?

[   10.541601] overlay_removal_is_ok: overlay #5 is not topmost
