Please also specify that commit's summary line in parens (or however you like).
that prevented qt2_process_read_urb() from trying to put chars into ttys that weren't actually opened. This resulted in 'tty is NULL' warnings from flush_to_ldisc() when the device was used.
The devices use just one read urb for all ports. As a result qt2_process_read_urb() may be called with the current port set to a port number that has not been opened. Add a check if the port is open before calling tty_flip_buffer_push().
