Hi Daniil

Could you work on SVACE and make it dump how it decided it was safe to
remove the NULL check. I assume it found the path via
sfp_register_socket(), and the NULL check in that. So it should be
able to dump that info in some form. sfp_bus_add_upstream() seems more
interesting and it would be interesting to know why it though a NULL
from there was impossible.

It would be great if the tool dumped some text which could be
cut/paste into the commit message as a justification for the change.
