Hi James,

this is an updated version of the patch. As I suspected, the issue isn't
quite as easy. Problem is that older SCSI-2 device have the habit for
responding to LUN1 in addition to LUN0, even though only one device is
attached. LUN1 has set PQ to 3 accordingly.
And of course we _don't_ want those fake devices to stick around.
So I've improved the logic to not register devices with LUN != 0 and a
PQ of 1 or 3. All other devices are registered accordingly.

I can't really see why we should register devices with PQ 1 and LUN !=
0; if one wants to have them he still can do a REPORT LUN on LUN 0 and
an explicit scan for the missing device.

And I do think the locking is slightly wrong for the failure case;
without this adaptecs have a habit of crashing when doing a rmmod.

But again, comments etc are welcome.

Cheers,

Hannes
