drm/amd/display: fix double free issue during amdgpu module unload
Details

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.
