   cpufreq/amd-pstate-ut: Fix an "Uninitialized variables" issue 
(2024-09-11 10:53:03 -0500)

----------------------------------------------------------------
second round of amd-pstate changes for 6.12 (second try):

* Move the calculation of the AMD boost numerator outside of
   amd-pstate, correcting acpi-cpufreq on systems with preferred cores
* Harden preferred core detection to avoid potential false positives
* Add extra unit test coverage for mode state machine
