[Dmitry Torokhov <dtor_core@ameritech.net>]

===================================================================


ChangeSet@1.1694, 2004-02-29 00:06:09-05:00, dtor_core@ameritech.net
  Firmware loader:
    We need to pin the firmware loader module until the last reference
    to the firmware class device is dropped and the class device is
    destroyed.
