You are right. Let me go over that once more and send a v2. I don't
believe in changing too many things at once and improvements or not,
it should be done separately (if anything to allow an easier revert
later on). :)

Actually, I think this is completely wrong. I asked AW on IRC (he was
away and I didn't wait; oops), but I'll Cc him here and Alexey as well
(who wrote the code).
Maybe I'm missing something, but it looks like this is passing the
absolute value of cap->tgt as a pointer. Shouldn't it just be
&cap->tg? I don't understand the casting to (void *). Later, in
vfio_pci_nvlink2_get_*, it does:
uint64_t val = (uintptr_t)opaque;
visit_type_unitXX(..., &val, ...);
It looks to me like that only gets the local variable and doesn't
return anything in practice. But again, I'm not familiar with this at
all so I may be saying non-sense.
If this is confirmed to be wrong, I can fix this in an extra patch in
this series. Thoughts welcome.
