From 4d8d4d251df8eaaa3dae71c8cfa7fbf4510d967d Mon Sep 17 00:00:00 2001 From: Chuck Ebbert Date: Wed, 24 Jun 2009 18:35:13 +0100 Subject: [PATCH] Remove low_latency flag setting from nozomi and mxser drivers The kernel oopses if this flag is set. [and neither driver should set it as they call tty_flip_buffer_push from IRQ paths so have always been buggy] Signed-off-by: Chuck Ebbert Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds --- drivers/char/mxser.c | 2 -- drivers/char/nozomi.c | 2 -- 2 files changed, 4 deletions(-) diff --git a/drivers/char/mxser.c b/drivers/char/mxser.c index 9533f43a30bb..52d953eb30c3 100644 --- a/drivers/char/mxser.c +++ b/drivers/char/mxser.c @@ -1048,8 +1048,6 @@ static int mxser_open(struct tty_struct *tty, struct file *filp) if (retval) return retval; - /* unmark here for very high baud rate (ex. 921600 bps) used */ - tty->low_latency = 1; return 0; } diff --git a/drivers/char/nozomi.c b/drivers/char/nozomi.c index d6102b644b55..574f1c79b6e6 100644 --- a/drivers/char/nozomi.c +++ b/drivers/char/nozomi.c @@ -1591,8 +1591,6 @@ static int ntty_open(struct tty_struct *tty, struct file *file) /* Enable interrupt downlink for channel */ if (port->port.count == 1) { - /* FIXME: is this needed now ? */ - tty->low_latency = 1; tty->driver_data = port; tty_port_tty_set(&port->port, tty); DBG1("open: %d", port->token_dl); -- 2.20.1
