Hi Linus,

Please pull from the tag

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-4.14-rc2

with top-most commit d84c97f8f77bc4124256e76864f125f45ad53744

Merge branches 'pm-cpufreq' and 'pm-cpuidle'

on top of commit 2bd6bf03f4c1c59381d62c61d03f6cc3fe71f66e

Linux 4.14-rc1

to receive power management fixes for v4.14-rc2.

These fix a cpufreq regression introduced by recent changes related
to the generic DT driver, an initialization time memory leak in
cpuidle on ARM, a PM core bug that may cause system suspend/resume
to fail on some systems, a request type validation issue in the PM
QoS framework and two documentation-related issues.

Specifics:

- Fix a regression in cpufreq on systems using DT as the source of
CPU configuration information where two different code paths
attempt to create the cpufreq-dt device object (there can be only
one) and fix up the "compatible" matching for some TI platforms
on top of that (Viresh Kumar, Dave Gerlach).

- Fix an initialization time memory leak in cpuidle on ARM which
occurs if the cpuidle driver initialization fails (Stefan Wahren).

- Fix a PM core function that checks whether or not there are any
system suspend/resume callbacks for a device, but forgets to
check legacy callbacks which then may be skipped incorrectly
and the system may crash and/or the device may become unusable
after a suspend-resume cycle (Rafael Wysocki).

- Fix request type validation for latency tolerance PM QoS requests
which may lead to unexpected behavior (Jan SchÃnherr).

- Fix a broken link to PM documentation from a header file and a
typo in a PM document (Geert Uytterhoeven, Rafael Wysocki).

Thanks!
