[PATCH v4 06/10] drm/i915: Use scope-based cleanup helper
From: Zihuan Zhang <hidden>
Date: 2025-09-03 13:18:22
Also in:
dri-devel, imx, intel-gfx, linux-acpi, linux-arm-kernel, linux-omap, linux-pm, lkml
Subsystem:
drm drivers, intel drm i915 driver (meteor lake, dg2 and older excluding poulsbo, moorestown and derivative), the rest · Maintainers:
David Airlie, Simona Vetter, Jani Nikula, Joonas Lahtinen, Rodrigo Vivi, Tvrtko Ursulin, Linus Torvalds
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.
