The only differences between Debian's source packages console-setup-1.221 and console-setup-1.222 are in the debian/changelog and in file debian/po/templates.pot where the value of POT-Creation-Date was changed.
So no further changes than updating debian/changelog and debian/po/templates.pot are needed when going from console-setup-1.221ubuntu2 to console-setup-1.221ubuntu1.
These changes are in appended file console-setup-1.222ubuntu1.diff.
Running dpkg-buildpackage -S -sa -d results in further changes in files
