clang warns because the added __maybe_unused attribute is in
the wrong place:

This might be the 3rd patch from 3 different people fixing the same
thing. Looks like I3C maintainer is on vacation. Please feel free to
send this trivial fix upstream some other way.

Isn't it already upstream?

This patch is fixing that one, the attribute was added between the
struct type, causing a new warning for clang.
I sent a fix for this earlier too, I do not care which one goes in as
long as one does so:

Ah yes, even after reading that 3 times, I got it wrong.

I was going to review and apply yours now that I have access to the i3c
repo. I must admit I didn't have a look at i3c patches until now and the
holiday season is not helping.
