Re: [PATCH 2/3] Blackfin Sports UART Driver: fix bug - the bugcaused by sport overrun, use timer to flip the tty buffer in order toreturn from rx ISR quickly

[Alan Cox]

Can you explain what the timer is for ? If you are trying to push the tty
processing out of the interrupt handler then surely schedule_work would
be sufficient. Also if you don't have tty->low_latency set the tty layer
will already do the actual processing work each timer event not in the
IRQ.
