Merge tag 'pm-urgent-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/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)"
