| |
tty->port is already set when rs_open is called given we linked it by tty_port_link_device(). If it wasn't, the tty layer would WARN loudly. So it's pointless to set it in rs_open. Instead, use the value in tty->port to find out the serial_state (info).
It's a fallout of commit b19e2ca77ee4 (TTY: use tty_port_link_device) which added tty_port_link_device here, but omitted to remove the tty->port assignment from rs_open.
