This doesn't apply anymore, due to other changes recently to this
driver.

But even if it did, I don't think it is correct.  I really don't
understand what you are trying to do here.  I think you just merged two
different major numbers togther, which isn't good at all.  But if you
didn't, then why is this patch doing different things to different files
(hint, only do one thing per file.)

Also, why does the driver have multiple major numbers?  Isn't a single
major good enough?  How many does it need?  For what does it use them
for?

Totally confused,
