Pali Rohár 7f840c1b26 serial: usbtty: Send urb data in correct order ... Function next_urb() selects the last urb data buffer from linked list to which next data from usbtty's puts function should be appended. But to check if TX data still exists it is needed to look at the first urb data buffer from linked list. So check for endpoint->tx_urb (first from the linked list) instead of current_urb (the last from the linked list). Successful call to udc_endpoint_write() may invalidate active urb and allocate new urb in queue which invalidates pointer returned by next_urb() function. So call next_urb() prior putting data into urb buffer and call it every time after using udc_endpoint_write() function to prevent sending data from usbtty's puts function in incorrect order. This patch fixes issue that usbtty code does not transmit data when they are waiting in the tx queue.
