From: Colin Ian King <colin.king@canonical.com>

There is an earlier check and return if err is non-zero, so
the check to see if it is zero is redundant in every iteration
of the loop and hence the check can be removed.

The subject and commit message are wrong. I think you copy-pasted them
from an earlier patch.
