Well ... this is actually wrong: scsi_add_device() returns an sdev on
success with the refcount bumped up for you.  If you don't do a put,
you'll be stuck with a device you can't get rid of.

However, all other users of scsi_add_device() make the same mistake ...
I'll apply this patch and fix the API to return zero or error and not
bump the sdev refcount.

James
