svn commit: r209680 - user/nwhitehorn/ps3/dev/ofw

[Nathan Whitehorn]

Author: nwhitehorn
Date: Sun Jul  4 02:42:01 2010
New Revision: 209680
URL: http://svn.freebsd.org/changeset/base/209680

Log:
  OF modules should return phandles equal to -1 on error, not 0. FDT should
  be audited for this more thoroughly, but this keeps Powermac-related
  stuff from thinking it should attach for now.
