8   Iterator that returns each device attached to <em class="parameter"><code>shost</code></em>.  It does _not_
9   take a reference on the scsi_device, so the whole loop must be
10   protected by shost-&gt;host_lock.

12   The only reason to use this is because you need to access the
13   device list in interrupt context.  Otherwise you really want to use
14   shost_for_each_device instead.
