We don't want the pr_info here - otherwise users can flood the logs. The
err code is sufficient.

Odd case here - your 16654 entry has a minimum of 8 so if I pass 1 then
it'll return -1 ? I guess for that case the best we can do is to set 8.
Other trivial thing to tweak - you have "uaser" in spot instead of "user".
With those two fixed it looks good to me.
