CVE-2023-53074
Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix ttm_bo calltrace warning in psp_hw_fini The call trace occurs when the amdgpu is removed after the mode1 reset. During mode1 reset, from suspend to resume, there is no need to reinitialize the ta firmware buffer which caused the bo pin_count increase redundantly.
