[PATCH 5.10 47/99] drm/amd/pm: fix a potential gpu_metrics_table memory leak

[Greg Kroah-Hartman]

From: Lang Yu <lang.yu@xxxxxxx>

[ Upstream commit aa464957f7e660abd554f2546a588f6533720e21 ]

Memory is allocated for gpu_metrics_table in renoir_init_smc_tables(),
but not freed in int smu_v12_0_fini_smc_tables(). Free it!

Fixes: 95868b85764a ("drm/amd/powerplay: add Renoir support for gpu metrics export")
