  * Module for AVM B1/M1/M2 PCMCIA-card.
  * 
  * (c) Copyright 1999 by Carsten Paeth (calle@calle.in-berlin.de)
  * 
  * $Log: b1pcmcia.c,v $
+ * Revision 1.5  1999/11/05 16:38:01  calle
+ * Cleanups before kernel 2.4:
+ * - Changed all messages to use card->name or driver->name instead of
+ *   constant string.
+ * - Moved some data from struct avmcard into new struct avmctrl_info.
+ *   Changed all lowlevel capi driver to match the new structur.
+ *
  * Revision 1.4  1999/08/22 20:26:26  calle
  * backported changes from kernel 2.3.14:
  * - several #include "config.h" gone, others come.
