4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: "Rafael J. Wysocki" <rafael.j.wysocki@xxxxxxxxx>
[ Upstream commit f451014692ae34e587b00de6745e16661cf734d8 ]
If new_policy is set in cpufreq_online(), the policy object has just
been created and its real_cpus mask has been zeroed on allocation,
and the driver's ->init() callback should not touch it.
It doesn't need to be cleared again, so don't do that.
