cpufreq: Explain the kobject_put() in cpufreq_policy_alloc()
It may not be particularly clear why the kobject_put() after failing kobject_init_and_add() in cpufreq_policy_alloc() is not redundant, so add a comment to explain that. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org>
