[patch 13/23] ieee1394: sbp2: enable auto spin-up for Maxtor disks

[Greg KH]

-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Stefan Richter <stefanr@xxxxxxxxxxxxxxxxx>

At least Maxtor OneTouch III require a "start stop unit" command after
auto spin-down before the next access can proceed.  This patch activates
the responsible code in scsi_mod for all Maxtor SBP-2 disks.
https://bugzilla.novell.com/show_bug.cgi?id=183011

Maybe that should be done for all SBP-2 disks, but better be cautious.
