I now realize that I should have mentioned the real motivation for this
change. I'm working on refactoring the code so that we can use ocxl in a
KVM guest. The concept of link can be shared by both powernv and pseries
variants but the SPA is definitely a powernv only thingy. The benefit
of this patch is hence to kick 'struct link' out of free_spa() so that
it can be utimately moved to powernv specific code.

The initial version of this change was just moving the link->spa check
and link->spa = NULL to the callers, where it was quite obvious they're
not needed... Should I re-post this as two patches for clarity ?  

Ah, that makes much more sense.

If that's the case, then why not go all the way and change the function 
signature while you're at it?

Sure, will do.
