Please build test your changes.

There is no 'ret' variable in this function, perhaps you meant 'err'.

Yes, obviously, this is 'err'.

I apologize. I usually build-test all my patches before submission.
This one seems to have gone out of my normal process.

Can you fix it yourself or do you want me to re-submit?
