Ok.

Yep...

I guess in some situations there where already a ret variable,
or in some I just forgot about it and did a strict string replacement.

I'll might change this to always ret, maybe as separate commit before
this one.

I'll have a look and fix this.

I'll extend the commit messages for these commits.

In the meantime I'll push patches up to:
s3:smbd: remove unused client_get_tcp_info()

Thanks very much for the review!
