## Overview

In the Linux kernel, the following vulnerability has been resolved:

usb: typec: class: Invalidate USB device pointers on partner unregistration

To avoid using invalid USB device pointers after a Type-C partner
disconnects, this patch clears the pointers upon partner unregistration.
This ensures a clean state for future connections.
