  * $Log: b1pci.c,v $
+ * Revision 1.18  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 1.17  1999/10/05 06:50:07  calle
+ * Forgot SA_SHIRQ as argument to request_irq.
+ *
  * Revision 1.16  1999/08/11 21:01:07  keil
