Subject: [PATCH net-next v3 4/5] net: altera_tse: explicitly disable autoscan on the regmap-mdio bus

Set the .autoscan flag to false on the regmap-mdio bus, to avoid using a
random uninitialized value. We don't want autoscan in this case as the
mdio device is a PCS and not a PHY.

Fixes: db48abbaa18e ("net: ethernet: altera-tse: Convert to mdio-regmap and use PCS Lynx")
Suggested-by: Russell King (Oracle) <rmk+kernel@...linux.org.uk>
