ACK patches 5-7, though I consider the above quoted statement somewhat
questionable... _why_ not hold a reference?
libata shouldn't affect the lifetime of the scsi device. When the sdev
disappears, dev->sdev should go too. It's easy to carry an extra
reference but it wouldn't mean anything - the reference will be
increased on attach and should be decreased with the device lifetime
reference, so I thought it would be better to make it explicit that
libata doesn't affect sdev's lifetime by not holding any extra reference
to it.
