Subject: [GIT PULL] Power management fixes for v5.10-rc3

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.10-rc3

with top-most commit 8c14577df4cd5c6d8b799bdfb3a0e94923f17d50

 Merge branches 'pm-cpufreq', 'pm-cpuidle', 'pm-opp' and 'powercap'

on top of commit 3cea11cd5e3b00d91caf0b4730194039b45c5891

 Linux 5.10-rc2

to receive power management fixes for 5.10-rc3.

These fix the device links support in runtime PM, correct mistakes in
the cpuidle documentation, fix the handling of policy limits changes
in the schedutil cpufreq governor, fix assorted issues in the OPP
(operating performance points) framework and make one janitorial
change.

Specifics:

 - Unify the handling of managed and stateless device links in the
   runtime PM framework and prevent runtime PM references to devices
   from being leaked after device link removal (Rafael Wysocki).

 - Fix two mistakes in the cpuidle documentation (Julia Lawall).

 - Prevent the schedutil cpufreq governor from missing policy
   limits updates in some cases (Viresh Kumar).

 - Prevent static OPPs from being dropped by mistake (Viresh Kumar).

 - Prevent helper function in the OPP framework from returning
   prematurely (Viresh Kumar).

 - Prevent opp_table_lock from being held too long during removal
   of OPP tables with no more active references (Viresh Kumar).

 - Drop redundant semicolon from the Intel RAPL power capping
   driver (Tom Rix).

Thanks!
