I think that is true for the majority of stuff we have under drivers/misc
anyway. I had done the same patch that Fabio sent a couple of months ago
but then forgot about it, so here is a wholehearted

Acked-by: Arnd Bergmann <arnd@xxxxxxxx>

for the new patch. It fixes a real problem, and we applied a similar patch
in drivers/mfd as 8a0a8e8e already. We probably still want to find a better
home for drivers that frequently get selected by other subsystems as you
said, but that is an independent issue. I don't see why anyone would
need a way to disable all MISC drivers at once, when the only thing that
(in theory) connects them is that they are all different from everything
else.
