Subject: [PATCH 1/2] drm/amd/pm: Fix a potential gpu_metrics_table memory leak
Date: Wed, 3 Aug 2022 17:19:58 +0800 [thread overview]
Message-ID: <20220803091959.10030-1-nizhen@uniontech.com> (raw)
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.
