Subject: net: phy: the NC-SI phy device do not require mdio bus
X-Git-Url: http://git.dujemihanovic.xyz/%7B%7B%20%24style.RelPermalink%20%7D%7D?a=commitdiff_plain;h=f146c446e51184a33deb798e8169aaf654c044a6;p=u-boot.git

net: phy: the NC-SI phy device do not require mdio bus

As with fixed-link phy device, the NC-SI phy devive does not
require an mdio bus. So, a condition is added to check the
NC-SI phy id to avoid accessing the bus pointer that is NULL.
