Thumbs up! This is a trivial change and only needs a single (R)eviewer.

Did you rerun the failing tests to make sure this is the only issue?

P.S.
I've done the "test a stack of patches" together and have something break
when you push just one of the patches... just recently in fact. :-(
At least yours didn't happen until Tier4... :-)
