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/generic_serial.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'drivers/char/generic_serial.c') diff --git a/drivers/char/generic_serial.c b/drivers/char/generic_serial.c index 7ed7da1d99c..f6610f28d65 100644 --- a/drivers/char/generic_serial.c +++ b/drivers/char/generic_serial.c @@ -586,8 +586,7 @@ void gs_close(struct tty_struct * tty, struct file * filp) port->flags &= ~GS_ACTIVE; - if (tty->driver->flush_buffer) - tty->driver->flush_buffer(tty); + gs_flush_buffer(tty); tty_ldisc_flush(tty); tty->closing = 0; -- cgit v1.2.3
