[PATCH] Char: tty_wakeup cleanup
tty_wakeup cleanup - remove wake_up_interruptible(&tty->write_wait) surrounding tty_wakup(tty); - substitute tty->ldisc.write_wakeup(tty) + wake_up() by tty_wakeup(tty); Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Acked-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
