I can see that for single lane function. But for lane-pair function,
it's not a new thing with nord, and the naming convention seems to be
without 'l', based on what I see from shikra, eliza, hawi and maili
drivers.

I understand that's mandatory for new feature changes, but for such
a bug fix where both binding and driver changes are closely coupled,
it seems more reasonable to not split.
