+Subject: [PATCH 45/73] drm/amd/pm: Fix a potential gpu_metrics_table memory
+ leak
+
+[ Upstream commit 5afb76522a0af0513b6dc01f84128a73206b051b ]
+
+Memory is allocated for gpu_metrics_table in
+smu_v13_0_4_init_smc_tables(), but not freed in
+smu_v13_0_4_fini_smc_tables(). This may cause memory leaks, fix it.
