From: Colin Ian King <colin.k...@canonical.com>
Variable ret is assigned to zero and is always zero throughout the
function. Thus the check for ret being less than zero is always
false and so mapping_set_error always has an -EIO error passed to
it. Hence we can remove the redundant assignment and check on ret.
