It seems as though fmt->sync_ep is not always set when this function is called hence the passing of the value at the call site. If this can be fixed, fmt->sync_up should be used as the wvalue. There doesn't seem to be a "cpu_to_le24" type function defined hence for the open code but I did see a similar thing done in Bluez lib. Perhaps we can get these definitions defined in byteorder.h. See hci_cpu_to_le24 in include/net/bluetooth/hci.h:2543 for similar usage.
