Pull power management fixes from Rafael Wysocki:
 "These fix three issues in the amd-pstate cpufreq driver.

  Specifics:

   - Remove checks for highest performance match on preferred cores when
     updating preferred core ranking in amd-pstate (Mario Limonciello)

   - Make amd-pstate call topology_logical_package_id() instead of
     logical_die_id() to get a socked ID for a CPU (Gautham Shenoy)

   - Fix uninitialized variable in amd_pstate_cpu_boost_update() (Dan
     Carpenter)"

* tag 'pm-6.11-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  cpufreq/amd-pstate-ut: Don't check for highest perf matching on prefcore
  cpufreq/amd-pstate: Use topology_logical_package_id() instead of logical_die_id()
  cpufreq: amd-pstate: Fix uninitialized variable in amd_pstate_cpu_boost_update()
