I see the following build error with COMPILE_TEST on randconfig builds: divers/built-in.o: In function `nsp_usb3_phy_init': phy-bcm-nsp-usb3.c:(.text+0x4050): undefined reference to `mdiobus_write' phy-bcm-nsp-usb3.c:(.text+0x406c): undefined reference to `mdiobus_write' phy-bcm-nsp-usb3.c:(.text+0x4088): undefined reference to `mdiobus_write' phy-bcm-nsp-usb3.c:(.text+0x40a4): undefined reference to `mdiobus_write' phy-bcm-nsp-usb3.c:(.text+0x40c0): undefined reference to `mdiobus_write' drivers/built-in.o:phy-bcm-nsp-usb3.c:(.text+0x40f2): more undefined references to `mdiobus_write' follow drivers/built-in.o: In function `mdio_module_init': phy-bcm-nsp-usb3.c:(.init.text+0x134): undefined reference to `mdio_driver_register' drivers/built-in.o: In function `mdio_module_exit': phy-bcm-nsp-usb3.c:(.exit.text+0xcc): undefined reference to `mdio_driver_unregister'
