#     Pull power management fixes from Rafael Wysocki:
#      "These fix two cpufreq issues, one in the intel_pstate driver and one
#       in the core.
#     
#       Specifics:
#     
#        - Prevent intel_pstate from avoiding to use HWP, even if instructed
#          to do so via the kernel command line, when HWP has been enabled
#          already by the platform firmware (Doug Smythies).
#     
#        - Prevent use-after-free from occurring in the schedutil cpufreq
#          governor on exit by fixing a core helper function that attempts to
#          access memory associated with a kobject after calling kobject_put()
#          on it (James Morse)"
#     
#     * tag 'pm-5.15-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
#       cpufreq: schedutil: Destroy mutex before kobject_put() frees the memory
#       cpufreq: intel_pstate: Override parameters if HWP forced by BIOS
