[PATCH 2/4] usb-storage: Associate the name of the interface with the scsi host

[Matthew Wilcox <matthew-Ztpu424NOJ8@public.gmane.org>]

From: Matthew Wilcox <willy-VuQAYsv1563Yd54FQh9/CA@public.gmane.org>

Instead of reporting "SCSI emulation for USB Mass Storage devices",
report "usb-storage 1-4:1.0".
