tty: Replace ASYNC_CTS_FLOW bit and update atomically
Replace ASYNC_CTS_FLOW bit in the tty_port::flags field with TTY_PORT_CTS_FLOW bit in the tty_port::iflags field. Add tty_port_set_cts_flow() helper to abstract the atomic bit ops. Signed-off-by: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
