Currently, all the tty drivers use a macro to extract an index to the
devices private cfdriver array from the dev_t that is formed from the
major/minor numbers and provided by the framework (and incidentally,
already stored in the tty structure as t_dev)

So what is your intention with this change? Are you changing the design
and if so, has that been discussed on a public list?

Having written tty drivers in the past, I do think this could do with a
redesign, but I also feel that all uses should remain consistent..
