Subject: [GIT PULL] Power management fixes for v6.15-rc5

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-6.15-rc5

with top-most commit 23203ed263f0701368468952d5004e320e5af6db

 Merge branch 'pm-cpufreq'

on top of commit b4432656b36e5cc1d50a1f2dc15357543add530e

 Linux 6.15-rc4

to receive power management fixes for 6.15-rc5.

These fix three recent regressions, two in cpufreq and one in the Intel
Soundwire driver, and an unchecked MSR access in the intel_pstate
driver:

 - Fix a recent regression causing systems where frequency tables are
   used by cpufreq to have issues with setting frequency limits (Rafael
   Wysocki).

 - Fix a recent regression causing frequency boost settings to become
   out-of-sync if platform firmware updates the registers associated
   with frequency boost during system resume (Viresh Kumar).

 - Fix a recent regression causing resume failures to occur in the
   Intel Soundwire driver if the device handled by it is in runtime
   suspend before a system-wide suspend (Rafael Wysocki).

 - Fix an unchecked MSR access in the intel_pstate driver occurring when
   CPUID indicates no turbo, but the driver attempts to enable turbo
   frequencies due to a misleading value read from an MSR (Srinivas
   Pandruvada).

Thanks!
