[PATCH v3 03/12] cpufreq: intel_pstate: Use scope-based cleanup helper
From: Zihuan Zhang <hidden>
Date: 2025-09-01 08:58:20
Also in:
dri-devel, imx, intel-gfx, linux-acpi, linux-arm-kernel, linux-omap, linux-pm, lkml
Subsystem:
cpu frequency scaling framework, intel pstate driver, the rest · Maintainers:

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.
