I want to use this interface in driver that I can't support to the
device model yet (i.e. due to lack of eisa/vlb hardware I can't add
ldm support to them, but we have common drivers).

I'm all for useful entries in sysfs, but what about doing that
implicitly in scsi_add_host when dev is null?  (and getting rid of the
separate __scsi_add_host)
