## Overview

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

drm/panel-edp: fix i2c adapter leak on probe failure

Make sure to drop the i2c adapter reference on probe failure (e.g.
probe deferral) and on driver unbind also if a devicetree redundantly
uses the 'ddc-i2c-bus' property to point to the aux ddc bus.

## Remediation

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