[PATCH 3.4 053/214] usb: storage: shuttle_usbat: fix discs being detected twice

From: Greg Kroah-Hartman
Date: Thu Jun 05 2014 - 01:05:43 EST

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


From: Daniele Forsi <dforsi@xxxxxxxxx>

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.
