- * uf_init_hw
- *
- * Resets hardware, downloads and initialises f/w.
- * This function demonstrates how to use the HIP core lib API
- * to implement the SME unifi_sys_wifi_on_req() part of the SYS API.
- *
- * In a simple implementation, all this function needs to do is call
- * unifi_init_card() and then unifi_card_info().
- * In the Linux implementation, it will retry to initialise UniFi or
- * try to debug the reasons if unifi_init_card() returns an error.
- *
- * Arguments:
- * ospriv Pointer to OS driver structure for the device.
- *
- * Returns:
- * O on success, non-zero otherwise.
