It was always possible to assign major device numbers dynamically.
I think what Jinesh wants to point out that , the parameer _dev itself
should not be used by driver developers.
It is something that should be obvious for the developer and treated
as a black-box , so to speak.
So is POSIX compiancy the ONLY reason the major and minor numebrs are present ?
