X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b943fbb09036bf7ff8e780af511a21576fe60a1e;p=openwrt%2Fstaging%2Fblogic.git

net: of/phy: fix build error when phylib is built as a module

CONFIG_OF_MDIO is tristate and will be m if PHYLIB is m.  Use
IS_ENABLED macro to prevent build error:

 ERROR: "of_mdio_find_bus" [drivers/net/phy/mdio-mux.ko] undefined!
