## Overview

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

drm/bridge: synopsys: dw-dp: Support unregistering the AUX channel

The DisplayPort AUX channel gets initialized and registered during
dw_dp_bind(), but it is never unregistered, which may lead to resource
leaks and/or use-after-free.

Add the missing dw_dp_unbind() function to allow the users of the
library to handle the required cleanup, i.e. unregister the AUX adapter.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
