I agree, you need to post code, even if it's not quite working, or
finished, as soon as possible.  Don't expect to wait until you are all
finished, and drop a whole new driver subsystem on us and think that it
will be instantly accepted.  It takes review time, and when you are
creating a whole new way to handle this hardware, it will take a few
tries to get it all correct.

So please, post code now, if possible.  But in the mean time, users will
continue to use this staging driver, as that is all that they have, so I
will not reject patches fixing and cleaning it up, as we really have no
way of knowing if anything else will ever end up in the kernel tree,
right?
