I have attached an updated combined patch of my previously posted sysfs
changes. 

This patch is against linux-scsi.bkbits.net/scsi-misc-2.5

This patch contains these updates:
	- update to osst.c to support sysfs cleanups.
	- oops fix in osst.c detach if no device attached. A better
	  method than this quick fix is needed.
	- removed scsi_bus_hotplug function do to bug and not really
	  needed now as default gives path data. If needed in future can
	  be added with better definition.
