drm/amdgpu/pm: fix the null pointer while the smu is disabled
Summary
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.
