That's fine, I have no objection to a total rewrite, that's happening
already to some drivers that are already in drivers/staging/. When
those drivers then go into the main kernel tree, I'll instantly drop the
drivers/staging/ driver.

I agree, but there are companies already using this code today. So why
not include it as it is useful to a very big group of users. If we get
it cleaned up and working better, that even helps out more.

Heh, how about explainations :)
