  22 **  This driver has been ported to Linux from the FreeBSD NCR53C8XX driver
  23 **  and is currently maintained by
  24 **
  25 **          Gerard Roudier              <groudier@free.fr>
  26 **
  27 **  Being given that this driver originates from the FreeBSD version, and
  28 **  in order to keep synergy on both, any suggested enhancements and corrections
  29 **  received on Linux are automatically a potential candidate for the FreeBSD
  30 **  version.
  31 **
  32 **  The original driver has been written for 386bsd and FreeBSD by
  33 **          Wolfgang Stanglmeier        <wolf@cologne.de>
  34 **          Stefan Esser                <se@mi.Uni-Koeln.de>
  35 **
  36 **  And has been ported to NetBSD by
  37 **          Charles M. Hannum           <mycroft@gnu.ai.mit.edu>
