## Overview

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

media: ipu-bridge: Fix null pointer deref on SSDB/PLD parsing warnings

When ipu_bridge_parse_rotation() and ipu_bridge_parse_orientation() run
sensor->adev is not set yet.

So if either of the dev_warn() calls about unknown values are hit this
will lead to a NULL pointer deref.

Set sensor->adev earlier, with a borrowed ref to avoid making unrolling
on errors harder, to fix this.

## Affected

- `linux_kernel >= 5.16, < 6.4.16`
- `linux_kernel >= 6.5, < 6.5.3`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.5.3`
