It was part of a series of 4 commits, basically there were 2 commits
from the series that had to be rolled back to make things work again
and this was one of the two. Sorry for the confusion. It turns out
that there was a change made some time ago (referenced by the Fixes:)
that broke how the clock was getting set for a specific clock, but
it wasn't until the patch series about the fractional dividers where
it went from "works despite being broken in this limited case" to
"doesn't work anymore in this limited case."

Thank you.
