Subject: realtek: mdio: drop dn attribute
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=e27ad8b4f6d4466cebd4009e82ab8ad6de082bbd;p=thirdparty%2Fopenwrt.git

realtek: mdio: drop dn attribute

The dn attribute was used to register the phys of the mdio bus
individually. With the new multiple busses this is not needed
any longer. Drop it.
