info->io_regsize = regsize ? *regsize : DEFAULT_REGSIZE;

[Please note that fixes a copy/paste bug, too].

There is no DEFAULT_REGSIZE, all the code is using  
DEFAULT_REGSPACING as the default size.
It looks like the code assumes that the registers are located next  
to each other.

It would be more logical to only use REGSIZE then, heh.

If thats not good, DEFAULT_REGSIZE should be introduced and used in  
all other probe functions as well.
That would be a seperate issue .

You could start the cleanup by doing

#define DEFAULT_REGSIZE DEFAULT_REGSPACING

and using REGSIZE in the new code.  Or replace s/REGSPACING/REGSIZE/
throughout.  Or something.

Not your fault though, just leave it as-is if you don't feel
like fixing others' mess :-)
