not a binding comment, though. Just for completeness, because we
are giving the version to the i2c and smbus, but not i3c.

The word "client" does not even appear in the documentation (only
one instance in the i3c document), so that the change is not
related to the document as stated in the commit log. Unless, of
course, I am missing something.

I'm OK with choosing a "customized" naming, but we need to reach
an agreement.

I raised the same question to Wolfram.
