Subject: net: phy: move registering mdio_bus_class and mdio_bus_type to libphy
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=25b23d82831870b8581abe6a24970ffd95675bc7;p=thirdparty%2Flinux.git

net: phy: move registering mdio_bus_class and mdio_bus_type to libphy

The MDIO consumer side shouldn't register class and bus_type.
Therefore move this to libphy.
