commit 715030c02051817b41139b87d8a13a71e55e5018
Author: Ian Kent <ikent@redhat.com>

autofs-5.0.6 - code analysis fixes 1
    
    Code analysis defect fixes, installment 1.
    
    - fix signed usage of unsigned variable in do_srv_query().
    - make NULL check handling of variable dcs explicit in get_dc_list().
      - adding an explicit NULL check for variable dcs gaurds against
        future changes in get_srv_rrs() returning success while not
        clearing the dcs variable.
      - makes it explict for readers why we don't need to check for NULL
        before free later in the loop.
    - fix typo in do_reconnect()
      - uri is never set now and, at this point, we need to try to connect
        to the last server uri (ctxt->uri->uri) which is set in find_server()
        when ctxt->uri is NULL.
