Subject[PATCH v7 1/6] cpufreq:amd-pstate: fix the nominal freq value set
Date
Address an untested error where the nominal_freq was returned in KHz
instead of the correct MHz units, this oversight led to a wrong
nominal_freq set and resued, it will cause the max frequency of core to
be initialized with a wrong frequency value.
