Lots of code is "flawed but works".  The place for such code is
drivers/staging/ - it gets put in there so the code is available for
those who need the driver and the code is later moved over into
drivers/ once the flaws have been addressed.

So a path forward here would be for us to put the driver and the
sglist extensions into a directory under drivers/staging/.
