Well, that's a totally different issue, because if we had used a
different variable for the other purpose, this assignment would
still be dead and coverity would still be whinging about it, no?
The problem that I have with this change (and the similar ones you've
made elsewhere) is really that it's only chance that the code isn't
fetching anything from the result of read_info. If we subsequently
wanted to change the logic so it did do that, we'd have to put back the
assignment. That sort of code churn benefits nobody.
