Its not obvious to me why using this new API requires you then to
set minors explicitly to 1, and yet here underneath we see the minors
argument passed is 0.

Nor is it clear from the documentation.
Basically for all new drivers no one should set minors at all, and the
dynamic dev_t mechanism does all the work.  For converted old drivers
minors is set manually instead of being passed an an argument that
should be 0 for all new drivers.
