Bluetooth: hci_uart: Use h4_recv_buf helper for Atheros AR300x
Instead of using hci_recv_stream_fragment, use the local available h4_recv_buf helper function. To ensure that the function is available select BT_HCIUART_H4. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
