linux-pm

Pull power management fix from Rafael Wysocki:
 "This fixes new breakage introduced by the most recent PM QoS fix in
  which, embarrassingly enough, I forgot to update
  dev_pm_qos_raw_read_value() to return the right default for devices
  with no PM QoS constraints at all which prevents runtime PM from
  suspending those devices (fix from Tero Kristo)"

* tag 'pm-urgent-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  PM / QoS: Fix default runtime_pm device resume latency
