You are right, its was removed. Ok, I will remove that line of the
comment too.

Well, I don't think it makes sense to print an additional error at this
point. The error will be propagated upwards in the call-chain and in the
end it is up to the initiator how to handle this situation (for example
just return a failure to user-space).
