Subject: [PATCH 3.12 058/146] usb: storage: shuttle_usbat: fix discs being detected twice

From: Daniele Forsi <dforsi@...il.com>

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

===============

commit df602c2d2358f02c6e49cffc5b49b9daa16db033 upstream.

Even if the USB-to-ATAPI converter supported multiple LUNs, this
driver would always detect the same physical device or media because
it doesn't use srb->device->lun in any way.
Tested with an Hewlett-Packard CD-Writer Plus 8200e.
