I guess it's better to have a more critical look at the arguments first.
Looking into dummy_hcd for instance, it doesn't appear like we need to
be int, it could be unsigned int. I just skimmed through the code, but
it looks like we will always hold >= 0 values on that variable.

So go through that exercise first, then we look at the others. Blindly
changing to min_t() might not give us any improvements at all ;-)
