Colin King reported a coverity error:
The variable ret is being assigned with a value that is never
read, it is being re-assigned the same value on the err0 exit
path. The assignment is redundant and hence can be removed.
He had a fix, but Andrew Davis suggested a better solution
(actually returning ret), so this patch implements that fix.
