All the current clients of this API assume that 0 corresponds
to a failure and non-zero to a pass therefore ignoring the need to
handle a negative error code.
This commit modifies the API to follow that standard since returning a
negative (EINVAL) doesn't seem to provide enough value to justify
the need to handle it.
