In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: fix double free issue during amdgpu module unload
Flexible endpoints use DIGs from available inflexible endpoints,
so only the encoders of inflexible links need to be freed.
Otherwise, a double free issue may occur when unloading the
amdgpu module.
