net: phy: Fix MDIO_THUNDER dependencies

ffainelli · davem330 · commit 665fff292332 · 2017-06-13T12:58:19.000-04:00
After commit 90eff90 ("net: phy: Allow splitting MDIO bus/device support from PHYs") we could create a configuration where MDIO_DEVICE=y and PHYLIB=m which leads to the following undefined references: drivers/built-in.o: In function `thunder_mdiobus_pci_remove': >> mdio-thunder.c:(.text+0x2a212f): undefined reference to >> `mdiobus_unregister' >> mdio-thunder.c:(.text+0x2a2138): undefined reference to >> `mdiobus_free' drivers/built-in.o: In function `thunder_mdiobus_pci_probe': mdio-thunder.c:(.text+0x2a22e7): undefined reference to `devm_mdiobus_alloc_size' mdio-thunder.c:(.text+0x2a236f): undefined reference to `of_mdiobus_register' Reported-by: kbuild test robot <fengguang.wu@intel.com> Fixes: 90eff90 ("net: phy: Allow splitting MDIO bus/device support from PHYs") Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Tested-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: David S.
