Merge tag 'pm-6.11-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
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()
