I'm trying to port my driver from 2.4 to 2.2. When I try to compile it, I get
several "multiple definition of `__module_kernel_version'" errors:

I've searched through the mailing list archives, but none of the "fixes"
suggested earlier seem to work. Why does this happen? And why doesn't it
happen with 2.4?
