[PATCH 5.19 45/72] drm/amd/pm: Fix a potential gpu_metrics_table memory leak
From: Greg Kroah-Hartman
Date: Fri Sep 02 2022 - 08:54:51 EST
From: Zhen Ni <nizhen@xxxxxxxxxxxxx>
[ 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.
