SHT::slave_alloc() return ignored sometimes

It is not clear what happens when a LLD returns non-zero to slave_alloc(). The scanning code in scsi_scan.c removes the device in one instance and ignores the returned value in 2 other instances. [lk 2.5.50]

Do we have other changes to the mid level - lower level interface planned (e.g. alternate method to queuecommand() )?
