## Overview

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

usb: typec: ucsi: displayport: Fix NULL pointer access

This patch ensures that the UCSI driver waits for all pending tasks in the
ucsi_displayport_work workqueue to finish executing before proceeding with
the partner removal.
