/*   FlashPoint.c -- FlashPoint SCCB Manager for Linux   This file contains the FlashPoint SCCB Manager from BusLogic's FlashPoint  Driver Developer's Kit, with minor modifications by Leonard N. Zubkoff for  Linux compatibility.  It was provided by BusLogic in the form of 16 separate  source files, which would have unnecessarily cluttered the scsi directory, so  the individual files have been combined into this single file.
