Subject: net: enetc: unregister mdiobus
X-Git-Url: http://git.dujemihanovic.xyz/img/static/gitweb.css?a=commitdiff_plain;h=7704b7fd673a603805f5ddd8807f69d4bc3b9188;p=u-boot.git

net: enetc: unregister mdiobus

If the device fails to probe - for example, when there is no
ethaddr set - then the private data is automatically freed
but the mdiobus remains registered.

Fixes: 1e354cb39314 ("drivers: net: fsl_enetc: register internal MDIO bus")
