  MFC 1.55:
      When in rev. 1.47 cardbus_alloc_resources() function was moved from
    cardbus_cis.c to this file, some code was not merged and thus resource
    list entries were invalid. They didn't have a resources attached to
    them.
      However, the problem was masked for some time later, because newer
    resources list entries were added to the head of the list, and
    resource_list_find() always returned the first matching resource list
    entry. Usually the underlying driver allocated a valid resource and
    added it to the head of the list, and invalid one wasn't used.
      In rev. 1.174 of subr_bus.c the sorting of resource list entries was
    reversed demasking the problem in cardbus_alloc_resources().
      This commit fixes the problem returning back some code from
    cardbus_cis.c, pre-1.49 revisions.
