--------------------------------

commit d13bc4d8 upstream.

This driver is for fairly obscure hardware, and has only seen random
drive-by changes after the maintainer stopped working on it in 2005
(about a year and a half after it was introduced).  It has some
"interesting" block layer interactions, so let's just drop it unless
anyone complains.
