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:

  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()
