Although ahc(4) has many quirks (to share sources among *BSD/Linux),
only aic7xxx_osm.c belongs to ahc(4) and it doesn't have any bad cast,
per output of grep adapt_dev sys/dev/ic/*.
(note aic79xx_osm.c is for ahd(4))

It's always better thing to device_private()'fy, but
the main trouble on device_t/softc split is that
it isn't easy to check actual types (device_t or softc)
against all (void *) pointers/arguments.

On the other hand, (void *) casts against device_t variables
are quite trivial.
