svn commit: r191054 - head/sys/dev/joy

[Ed Schouten]

Author: ed
Date: Tue Apr 14 11:23:09 2009
New Revision: 191054
URL: http://svn.freebsd.org/changeset/base/191054

Log:
  Use si_drv1 to store joy(4)'s softc.
  
  There are still some calls to dev2unit() left, but I guess we should
  take care of those another time.
