It concerns a reference leak of prev_sink in the AMD Display link-detection path when the USB-C DP alt-mode wait times out (detect_link_and_local_sink). The link-detection code carrying this function and its USB-C DP alt-mode timeout path was introduced upstream after the 4.19 base; neither the function nor the alt-mode wait helper exist in this kernel's amdgpu display code.",
