clean the code by using the ifmap instead of plain fields,
and avoid code duplication.

That's not the only driver that'd need to be changed.
Try building the kernel with allmodconfig.

base_addr was unsigned long now its unsigned short.
IDK if that matters.

I'd rather we didn't mess with this code - it's only used by ancient
