[PATCH] USB Storage: remove dependency on SCSI-provided serial/tag number
This patch started life as as531 from Alan Stern. It has been rediffed
against the latest tree.
The SCSI people have deprecated the use of scsi_cmnd.serial_number for
anything other than printk. Worse than that, the SCSI core doesn't
always increment the number (when the error handler is running, for
example). So this patch creates a locally-stored value for use in
bulk-only tags. The net result is a simplification, since we no longer
have to save & restore the serial_number value while autosensing.
