When trying to figure out why the "uhci-hcd" driver was so
much bigger than "usb-uhci-hcd" I noticed that most of it
was the /proc/driver/uhci support, and that if I tried to
disable it, I got compile-time warnings about things that
were defined but not referenced.
This patch makes that procfs support cleanly vanish if it's
configured out. Please merge to Linus' latest.
(However, I suspect this should probably also be controlled
by the general USB debug support flag.)
