I'll look at that for a second round of cleanup once all of the
round_rates have been removed from the tree. From what I recall about
the ~200 or so round_rate implementations in the kernel tree, there
were maybe only 5 or so that cover this noop case. QC seemed to have
the most from what I recall.

It wouldn't be hard to make a Coccinelle script to look for the noop
determine_rate() implementations.
