Fix warning for: drivers/cpufreq/intel_pstate.c:731 store_energy_performance_preference() error: uninitialized symbol 'epp'.
This warning is for a case, when energy_performance_preference attribute matches pre defined strings. In this case the value of raw epp will not be used to set EPP bits in MSR_HWP_REQUEST. So initializing with any value is fine.
