New Revision: 184581
URL: http://svn.freebsd.org/changeset/base/184581

Log:
  Use child (the card) in preference to cbdev (the bridge) when
  allocating resources to read the CIS.  I'm not sure when this changed,
  but it is totally wrong.  Also, add a minor improvement to the
  debugging.
  
  This should help everybody trying to run dumpcis on atheros wireless
  card as well.
