Just call make-kpkg again as before, something like

fakeroot make-kpkg --initrd --revision XYZ kernel_image

The kernel Makefile will catch your changes and only recompile what is
needed. If I understand correctly, the debian sub-directory will be
recreated on the fly. It should be safe to remove it, though, if the
above does not work out. dpkg will yell out some warnings when you
install the newly built version as it is not able to determine new
module dependencies. In this case, just recompiling a single module,
there shouldn't be a problem.
