## Overview

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

net: mhi: Fix memory leak in mhi_net_dellink()

MHI driver registers network device without setting the
needs_free_netdev flag, and does NOT call free_netdev() when
unregisters network device, which causes a memory leak.

This patch calls free_netdev() to fix it since netdev_priv
is used after unregister.

## Affected

- `Linux >= 13adac032982c61bb590669e8e87e51558917ca1 < 88da008e5e2f9753726ea5a51ef2eb144e9de927`
- `Linux >= 13adac032982c61bb590669e8e87e51558917ca1 < 25a270343b0f16e1f6e65f541a15975a35e238ff`
- `Linux >= 13adac032982c61bb590669e8e87e51558917ca1 < f7c125bd79f50ec6094761090be81d02726ec6f4`
- `Linux 5.14`
