[PATCH v5 5/6] drm/i915: Use scope-based cleanup helper
Posted by Zihuan Zhang 4 days, 16 hours ago
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.
