I am not calling this function in my driver atall, this is getting called by 
tty_port.c

int tty_port_block_til_ready(struct tty_port *port,
                               struct tty_struct *tty, struct file *filp)
{
/* Probe the carrier. For devices with no carrier detect this
                  will always return true */
               cd = tty_port_carrier_raised(port);
               if (!(port->flags & ASYNC_CLOSING) &&
                               (do_clocal || cd))
                       break;
               if (signal_pending(current)) {
                       retval = -ERESTARTSYS;
                       break;
               }
