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

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:

Qasim Ijaz (4):
  fix uninitialised access in mii_nway_restart()
  remove extraneous return in control_write() to propagate failures
  improve error handling in get_mac_address()
  add error handling in ch9200_bind()
