Subject: [PATCH 0/5] net: ch9200: fix various bugs and improve qinheng ch9200 driver

This patch series aims to fix various issues throughout the QinHeng CH9200
driver. This driver fails to handle various failures, 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, Simon Horman and Jakub Kicinski you can view those
discussions below:

Qasim Ijaz (5):
  fix uninitialised access bug during mii_nway_restart
  remove extraneous return that prevents error propagation
  fail fast on control_read() failures during get_mac_address()
  add missing error handling in ch9200_bind()
  avoid triggering NWay restart on non-zero PHY ID
