    Subjecttty->low_latency + irq context
    Hi!

    * tty_flip_buffer_push - terminal
    * @tty: tty to push
    *
    * Queue a push of the terminal flip buffers to the line discipline. This
    * function must not be called from IRQ context if tty->low_latency is set.

    But some drivers (mxser, nozomi, hvsi...) sets low_latency to 1 in _open and
    calls tty_flip_buffer_push in isr or in functions, which are called from isr.
    Is the comment correct or the drivers?

    Moreover, hvsi says:
    tty->low_latency = 1; /* avoid throttle/tty_flip_buffer_push race */

    thanks,
