- register softc of child devices as an argument of the sio interrupt handler to avoid device_lookup_private() calls on every interrupt - change type of sc_reg from (void *) to (struct sioreg *) to avoid weird address offset calculations with redundant casts - rename struct sio_softc members for consistency - use a channel number passed via sio_attach_args in lunaws_attach() No functional chnages. Tested on LUNA.
