Subject: [GIT PULL] More power management updates for v5.2-rc1

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.2-rc1-2

with top-most commit 2a8d69f6139b605b2e36c80540cb8e8da2d016be

 Merge branches 'pm-cpufreq' and 'pm-domains'

on top of commit 8f5e823f9131a430b12f73e9436d7486e20c16f5

 Merge tag 'pm-5.2-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

to receive additional power management updates for 5.2-rc1.

These fix a recent regression causing kernels built with CONFIG_PM
unset to crash on systems that support the Performance and Energy
Bias Hint (EPB), clean up the cpufreq core and some users of
transition notifiers and introduce a new power domain flag into
the generic power domains framework (genpd).

Specifics:

 - Fix recent regression causing kernels built with CONFIG_PM
   unset to crash on systems that support the Performance and
   Energy Bias Hint (EPB) by avoiding to compile the EPB-related
   code depending on CONFIG_PM when it is unset (Rafael Wysocki).

 - Clean up the transition notifier invocation code in the cpufreq
   core and change some users of cpufreq transition notifiers
   accordingly (Viresh Kumar).

 - Change MAINTAINERS to cover the schedutil governor as part of
   cpufreq (Viresh Kumar).

 - Simplify cpufreq_init_policy() to avoid redundant computations
   (Yue Hu).

 - Add explanatory comment to the cpufreq core (Rafael Wysocki).

 - Introduce a new flag, GENPD_FLAG_RPM_ALWAYS_ON, to the generic
   power domains (genpd) framework along with the first user of it
   (Leonard Crestez).

Thanks!
