New Revision: 249073
URL: http://svnweb.freebsd.org/changeset/base/249073

Log:
  Resolve kernel panic that occurs on callback from sysctl when setting
  hw.ciss.expose_hidden_physical=1 on a HP ProLiant DL360 G6 (and possibly
  others) due to mishandling of error value in acpica on stable/7
  
  Note that this is a direct commit as this code has been fixed in stable/8
  (8.4 included) and higher release for quite some time.
