    net: phy: rework Kconfig settings for MDIO_BUS · 4c3464a8
    Arnd Bergmann authored
    I still see build errors in randconfig builds and have had this
    patch for a while to locally work around it:
    
    drivers/built-in.o: In function `xgene_mdio_probe':
    mux-core.c:(.text+0x352154): undefined reference to `of_mdiobus_register'
    mux-core.c:(.text+0x352168): undefined reference to `mdiobus_free'
    mux-core.c:(.text+0x3521c0): undefined reference to `mdiobus_alloc_size'
    
    The idea is that CONFIG_MDIO_BUS now reflects whether the mdio_bus
    code is built-in or a module, and other drivers that use the core
    code can simply depend on that, instead of having a complex
    dependency line.
