I'm a strong believer of "evolutionary" approach. Patch sets for the
most part (everything in the end has to be considered case by case, not
a strict rule) should have some functional changes involved.

What I do require for the parts that I maintain is that any new change
will result cleaner code base than the one that existed before that
change was applied. Again, there are some exceptions to this e.g.
circulating a firmware bug but this is my driving guideline as a
maintainer.

Doing cleanups just for cleanups can sometimes add unnecessary merge
conflicts when backporting patches to stable kernels. Thus, if you are
doing just a cleanup you should have extremely good reasons to do so.
