The commit is a regression fix during the 5.2 cycle, how it could end up
in a 4.19 stable candidate?

$ git describe 03628cdbc64db6

$ git describe --contains 03628cdbc64db6

And it does not belong to 5.2 either, git cherry-pick on top of 5.2

I think such sanity check can be done automatically so the patches don't
accidentally land in trees where don't belong.
