In this case it's actually not needed though. Some of the in-flight content for 6.14 drops that variable. This is on the superm1/linux.git bleeding-edge branch (which content will promote to superm1/linux.git linux-next branch soon and eventually come to linux-pm). https://git.kernel.org/pub/scm/linux/kernel/git/superm1/linux.git/commit/?h=bleeding-edge&id=b8321230569dc17852a7f7adc7715ad07538cbeb

epp_policy uses the same values as cpufreq_policy.policy and resets to CPUFREQ_POLICY_UNKNOWN during offlining. Be consistent about it and initialize to CPUFREQ_POLICY_UNKNOWN instead of 0, too. No functional change intended.
