Linus Torvalds 4357f03d66 Power management fixes for 5.15-rc2 
- 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).

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)"
