  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.
