driver(9)

According to driver(9), the interface to driver “foo” is defined with:

     CFATTACH_DECL_NEW(foo,                  /* driver name */

    Introduce CFATTACH_DECL_NEW and CFATTACH_DECL2_NEW for drivers that
    don't expect struct device as first field of softc. device_private uses
    a new field of struct device to give the softc address and that field is
    either set the struct device for old-style devices or a separate
    allocation by config_devalloc. Both macros are intended as temporary
    bandaid until all drivers are converted and will be removed later.


yet the next paragraph still mentions CFATTACH_DECL and declares sc_dev.

Apply the following (which leaves an odd struct foo_softc declaration)?
