2009-07-03sh-sci: update receive error handling for muxed irqsMagnus Damm
This patch updates the receive error code for muxed interrupts in the sh-sci driver. Receive error interrupts may be generated by the hardware if RE or REIE bits in SCSCR are set. Update the muxed interrupt handling code to acknowledge error interrupts if RE or REIE is set, instead of only acknowledging if REIE is set. Without this patch error interrupts may be generated but never acked resulting in a "nobody cared" crash. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-06-22serial: fix off by one errorsRoel Kluin
In zs_console_putchar() occurs: if (zs_transmit_drain(zport, irq)) write_zsdata(zport, ch); However if in zs_transmit_drain() no empty Tx Buffer occurs, limit reaches -1 => true, and the write still occurs. This patch changes postfix to prefix decrements in this and similar functions to prevent similar mistakes in the future. This decreases the iterations with one but the chosen loop count was arbitrary anyway. In sunhv limit reaches -1, not 0, so the test is off by one.

2009-06-16atmel_serial: fix hang in set_termios when crtscts is enabledHaavard Skinnemoen
After enabling hardware flow control, any subsequent termios call may hang waiting for the transmitter to drain. This appears to be caused by a busy-loop in set_termios() waiting for the transmitter to become empty, which may take a very long time (or hang indefinitely) if the device at the other end is blocking us. A quick look through the tty and serial_core code indicates that any necessary flushing (which is optional) has already been done at this point, so there's no need for the driver to flush the transmitter on its own. Fix it by removing the busy-loop altogether.
