RFC: 2.6: unused code under drivers/message/fusion/

[Adrian Bunk]

I know this patch is wrong, but I'd like to note that it actually 
changes nothing since all code removed or made static currently has no 
in-kernel users (there seems to be a mptstm.c missing?).

Please comment on how to correctly handle this.
