This is why I think %pIS should have an option
to print port/flow, etc.

In this case it's using v4 and you are mixing
unknown and known forms.  It looks untidy.
You should probably use peer->sa.sin_port instead.

here too, but port may be unused when !CONFIG_DEBUG

I didn't look at the rest of the patch.
