Zhipeng Lu a658270117 drm/amd/pm: fix a double-free in amdgpu_parse_extended_power_table ... The amdgpu_free_extended_power_table is called in every error-handling paths of amdgpu_parse_extended_power_table. However, after the following call chain of returning: amdgpu_parse_extended_power_table |-> kv_dpm_init / si_dpm_init (the only two caller of amdgpu_parse_extended_power_table) |-> kv_dpm_sw_init / si_dpm_sw_init (the only caller of kv_dpm_init / si_dpm_init, accordingly) |-> kv_dpm_fini / si_dpm_fini (goto dpm_failed in xx_dpm_sw_init) |-> amdgpu_free_extended_power_table As above, the amdgpu_free_extended_power_table is called twice in this returning chain and thus a double-free is triggered. Similarily, the last kfree in amdgpu_parse_extended_power_table also cause a double free with amdgpu_free_extended_power_table in kv_dpm_fini.
