Description
A reference leak vulnerability was identified and fixed in the Linux kernel's drm/rockchip analogix_dp driver. The issue involved improper management of device node references in the function rockchip_dp_drm_encoder_enable(), where of_get_child_by_name() calls were not symmetrically paired with of_node_put(), leading to a resource leak. The fix introduces automatic cleanup of device nodes to prevent the leak.
