From d796558def777f9a9cc274861e06b8b61851b409 Mon Sep 17 00:00:00 2001 From: Yang Wang Date: Sat, 9 May 2026 15:20:39 +0800 Subject: [PATCH] drm/amd/pm: fix memleak of dpm_policies on smu v15 In smu_v15_0_fini_smc_tables, dpm_policies was not freed or NULLed, causing a memory leak. Add kfree() and NULL assignment to properly release memory and avoid dangling pointers.
