tty: r3964: Use tty->read_wait waitqueue
The tty core provides read_wait waitqueue specifically for line disciplines to wait readers; otherwise, the line discipline may miss wakeups generated by the tty core. NB: The tty core already provides serialization for the line discipline's close() method, and guarantees no readers or writers will be using the closing instance of the line discipline. Completely remove that wakeup. Signed-off-by: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
