Subject[PATCH v4 06/10] drm/i915: Use scope-based cleanup helper
Date
Replace the manual cpufreq_cpu_put() with __free(put_cpufreq_policy)
annotation for policy references. This reduces the risk of reference
counting mistakes and aligns the code with the latest kernel style.

No functional change intended.
