Subject: [GIT PULL] Power management fixes for v5.13-rc2

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.13-rc2

with top-most commit 78a6948bbadd0da46d318f3b7a954a71e02c39f7

 Merge branch 'pm-core'

on top of commit 6efb943b8616ec53a5e444193dccf1af9ad627b5

 Linux 5.13-rc1

to receive power management fixes for 5.13-rc2.

These close a coverage gap in the intel_pstate driver and fix
runtime PM child count imbalance related to interactions with
system-wide suspend.

Specifics:

 - Make intel_pstate work as expected on systems where the platform
   firmware enables HWP even though the HWP EPP support is not
   advertised (Rafael Wysocki).

 - Fix possible runtime PM child count imbalance that may
   occur if other runtime PM functions are called after invoking
   pm_runtime_force_suspend() and before pm_runtime_force_resume()
   is called (Tony Lindgren).

Thanks!
