No.. At the very least, do something like the attached patch. Preferably
go further and use 'struct isa_pnp_id sbc_ids[]' and
error = ISA_PNP_PROBE(device_get_parent(dev), dev, sbc_ids);
if (error == ENXIO)
return ENXIO;
...
Also, don't add the children until attach time. There is no guarantee that
just because your probe succeeded that you'll actually be attached, something
else might out-bid you for the device id.

There is no pnpinfo for it. It has a logical device ID only with no vendor ID.
Minimal patch appended..
Cheers,
