From 978e595f88a1fba5869aa42a4af4fba36f33ecac Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Wed, 30 Apr 2008 00:53:59 -0700 Subject: tty/serial: lay the foundations for the next set of reworks - Stop drivers calling their own flush method indirectly, it obfuscates code and it will change soon anyway - A few more lock_kernel paths temporarily needed in some driver internal waiting code - Remove private put_char method that does a write call for one char - we have that anyway - Most but not yet all of the termios copy under lock fixing (some has other dependencies to follow) - Note a few locking bugs in drivers found in the process - Kill remaining [ab]users of TIOCG/SSOFTCAR in the driver, these must go to fix the termios locking Signed-off-by: Alan Cox Cc: Jiri Slaby Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/char/serial167.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'drivers/char/serial167.c') diff --git a/drivers/char/serial167.c b/drivers/char/serial167.c index f62fb9360c3f..62d6f2e0fd18 100644 --- a/drivers/char/serial167.c +++ b/drivers/char/serial167.c @@ -1674,8 +1674,7 @@ static void cy_close(struct tty_struct *tty, struct file *filp) if (info->flags & ASYNC_INITIALIZED) tty_wait_until_sent(tty, 3000); /* 30 seconds timeout */ shutdown(info); - if (tty->driver->flush_buffer) - tty->driver->flush_buffer(tty); + cy_flush_buffer(tty); tty_ldisc_flush(tty); info->tty = NULL; if (info->blocked_open) { -- cgit v1.2.3
