## Overview

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

platform/x86: lg-laptop: Fix LED resource handling

The event notification callback might access kbd_backlight even
when it was not successfully registered with the LED subsystem.
The same happens inside acpi_remove(), where the LED devices are
unregistered unconditionally.

Fix this by tracking the availability of the kbd_backlight LED
device and use devm_led_classdev_register() to let devres take
care of unregistering the LED devices during removal. For this
the parent device of the LED devices is changed to the native
platform device.

## Remediation

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