[PATCH 0/4] net: fix bugs and error handling in qinheng ch9200 driver and mii interface

[Qasim Ijaz <qasdev00@gmail.com>]

This patch series aims to fix various issues throughout the QinHeng CH9200
driver. This driver fails to handle failures throughout, which in one
case has lead to a uninit access bug found via syzbot. Upon reviewing
the driver I fixed a few more issues which I have included in this patch
series.

Parts of this series are the product of discussions and suggestions I had
from others like Andrew Lunn and Simon Horman, you can view those
discussions below:
