Seems correct.

I feel like RequiredSlots is not actually used anywhere in the code,
just passed around dml32_TruncToValidBPP() and
dml32_CalculateOutputLink(). I've looked for any mentions of it in the
mailing list, but could not find anything that implied it's part of
ground working. I wonder if it's something outside the Linux tree for
other platforms or related to HW gospel.
