Subject: [PATCH] [SCSI] zfcp: Remove SCSI devices when removing complete
adapter
The common I/O layer can call remove a handler to inform zfcp
that a device disappeared. The handler zfcp_ccw_remove then
removes all unit, port and the adapter data structures. Removing
the units requires that the SCSI devices are removed first.
