2.5.56: Two global symbols "io"

[Adrian Bunk]

I got the following compile error in 2.5.56:

	Just change it to "static". This has been reported before
by Arnd Bergmann from the Kernel Janitors Project. However: cosa.c
can be built as a module only. Linus, please apply this.

Ups, sorry, that was again the "Kconfig doesn't handle && m in kernels 
without module support" bug (#269 at bugzilla.kernel.org).
