Looks up the scsi_device with the specified <em class="parameter"><code>lun</code></em> for a given
<em class="parameter"><code>starget</code></em>. The returned scsi_device does not have an additional
reference. You must hold the host's host_lock over this call and
any access to the returned scsi_device. A scsi_device in state
SDEV_DEL is skipped.
</p></div><div class="refsect1" title="Note"><a id="id2698233"></a><h2>Note</h2><p>
The only reason why drivers should use this is because
they need to access the device list in irq context. Otherwise you
really want to use scsi_device_lookup_by_target instead.
