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.
