Subject: [GIT PULL][Resend] Power management updates for v5.11-rc2

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.11-rc2

with top-most commit 89ecf09e0b93de54415de45be241649ec1b162de

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

on top of commit 5c8fe583cce542aa0b84adc939ce85293de36e5e

 Linux 5.11-rc1

to receive power management updates for 5.11-rc2.

These fix a crash in intel_pstate during resume from suspend-to-RAM
that may occur after recent changes and two resource leaks in error
paths in the operating performance points (OPP) framework, add a new
C-states table to intel_idle and update the cpuidle MAINTAINERS entry
to cover the governors too.

Specifics:

 - Fix recently introduced crash in the intel_pstate driver that
   occurs if scale-invariance is disabled during resume from
   suspend-to-RAM due to inconsistent changes of APERF or MPERF
   MSR values made by the platform firmware (Rafael Wysocki).

 - Fix a memory leak and add a missing clk_put() in error paths in
   the OPP framework (Quanyang Wang, Viresh Kumar).

 - Add new C-states table for SnowRidge processors to the intel_idle
   driver (Artem Bityutskiy).

 - Update the MAINTAINERS entry for cpuidle to make it clear that
   the governors are covered by it too (Lukas Bulwahn).

Thanks!
