Zhipeng Lu adc0a5378d drm/amd/pm: fix a double-free in si_dpm_init ... [ Upstream commit ac16667237a82e2597e329eb9bc520d1cf9dff30 ] [tapd] https://tapd.woa.com/TS4Q/prong/stories/view/1020422414118043047 This fixes CVE-2023-52691 When the allocation of adev->pm.dpm.dyn_state.vddc_dependency_on_dispclk.entries fails, amdgpu_free_extended_power_table is called to free some fields of adev. However, when the control flow returns to si_dpm_sw_init, it goes to label dpm_failed and calls si_dpm_fini, which calls amdgpu_free_extended_power_table again and free those fields again. Thus a double-free is triggered.
