## Overview

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

octeon_ep: fix potential memory leak in octep_device_setup()

When occur unsupported_dev and mbox init errors, it did not free oct->conf
and iounmap() oct->mmio[i].hw_addr. That would trigger memory leak problem.
Add kfree() for oct->conf and iounmap() for oct->mmio[i].hw_addr under
unsupported_dev and mbox init errors to fix the problem.

## Affected

- `Linux >= 862cd659a6fbac664f1fcdd7149046040a7a7e9c < 67b65a0db8a7fdad43159819f41335497a4bb04f`
- `Linux >= 862cd659a6fbac664f1fcdd7149046040a7a7e9c < e4041be97b15302ebfffda8bbd45f3b2d096048f`
- `Linux 5.19`
