    Vitaly Bordug authored
    device_bind_driver() error code returning has been fixed.  release()
    function has been written, so that to free resources in correct way; the
    release path is now clean.
    Before the rework, it used to cause
     Device 'fixed@100:1' does not have a release() function, it is broken
     and must be fixed.
     BUG: at drivers/base/core.c:104 device_release()
     Call Trace:

    Also changed the notation of the fixed phy definition on
    mdio bus to the form of <speed>+<duplex> to make it able to be used by
    gianfar and ucc_geth that define phy_id strictly as "%d:%d" and cleaned up
    the whitespace issues.
