The valid cpumask range is [0, nr_cpu_ids) and cpumask_next() always returns a CPU ID greater than its input, which results in its input range being [-1, nr_cpu_ids - 1). Ensure showing CPU info avoids triggering error conditions in cpumask_next() by stopping its loop
What error conditions?
What would happen if @n is outside of the valid range?
