From: "Rafael J. Wysocki" <rafael.j.wysocki@intel.com>

Call cpu_latency_qos_add/update/remove_request() instead of
pm_qos_add/update/remove_request(), respectively, because the
latter are going to be dropped.

No intentional functional impact.

Heh, that's careful, I usually boldly claim "no functional changes" on
