  * Module for AVM B1 ISA-card.

  * $Log: b1isa.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 20:26:24  calle
  * backported changes from kernel 2.3.14:
  * - several #include "config.h" gone, others come.
