Variable ret is not deleted, the commit message is misleading.

FWIW I've noticed that my Reviewed-by tag was added to the accepted change,
while it was the conditional one... Actually I don't know how to be aware
of such nuances, if only b4 tool is used, likely there is no way for it.

Hopefully I'm not too picky with it.

If it still matters, this one apparently unnoticed candidate would
have been a better choice:

I thought the change that made your r-b conditional was the
Fixes tag, right? That is added. Have I missed anything?

(I noticed later the v3, but it's basically identical to the one
I pushed).

Absolutely not! Please, keep pinging me if you see anything I
might have missed.

ah, no, it was about the copy-pasted commit message, which mentions a much
more popular 'ret' local variable.

Well, I believe my concern about a commit message has quite low significance,
so let it be kept as is, the most essential code change part is untouched.

oh yes, the new commit message says:

"Variable cci_clk_rate is not effectively used, so delete it."

I'm sorry, I will fix it.
