## Overview

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

drm/msm/adreno: Fix a reference leak in a6xx_gpu_init()

In a6xx_gpu_init(), node is obtained via of_parse_phandle().
While there was a manual of_node_put() at the end of the
common path, several early error returns would bypass this call,
resulting in a reference leak.
Fix this by using the __free(device_node) cleanup handler to
release the reference when the variable goes out of scope.

Patchwork: https://patchwork.freedesktop.org/patch/700661/

## Affected

- `linux_kernel >= 6.5, < 7.0.11`
- `linux_kernel = 7.1`

## Remediation

Upgrade past the affected range:

- `linux_kernel 7.0.11`
