Merge tag 'pm-6.14-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more power management updates from Rafael Wysocki:
 "These are mostly fixes on top of the previously merged power
  management material with the addition of some teo cpuidle governor
  updates, some of which may also be regarded as fixes:

   - Add missing error handling for syscore_suspend() to the hibernation
     core code (Wentao Liang)

   - Revert a commit that added unused macros (Andy Shevchenko)

   - Synchronize the runtime PM status of devices that were runtime-
     suspended before a system-wide suspend and need to be resumed
     during the subsequent system-wide resume transition (Rafael
     Wysocki)

   - Clean up the teo cpuidle governor and make the handling of short
     idle intervals in it consistent regardless of the properties of
     idle states supplied by the cpuidle driver (Rafael Wysocki)

   - Fix some boost-related issues in cpufreq (Lifeng Zheng)

   - Fix build issues in the s3c64xx and airoha cpufreq drivers (Viresh
     Kumar)

   - Remove unconditional binding of schedutil governor kthreads to the
     affected CPUs if the cpufreq driver indicates that updates can
     happen from any CPU (Christian Loehle)"
