Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/pm: fix the null pointer while the smu is disabled
It needs to check if the pp_funcs is initialized while release the context, otherwise it will trigger null pointer panic while the software smu is not enabled.
