- * FILE: csr_wifi_hip_card_udi.c
- *
- * PURPOSE:
- * Maintain a list of callbacks to log UniFi exchanges to one or more
- * debug/monitoring client applications.
- *
- * NOTES:
- * Just call the UDI driver log fn directly for now.
- * When done properly, each open() on the UDI device will install
- * a log function. We will call all log fns whenever a signal is written
- * to or read form the UniFi.
