tty: Fix TIOCGPTPEER ioctl definition
This ioctl does nothing to justify an _IOC_READ or _IOC_WRITE flag because it doesn't copy anything from/to userspace to access the argument. Fixes: 54ebbfb16034 ("tty: add TIOCGPTPEER ioctl") Signed-off-by: Gleb Fotengauer-Malinovskiy <glebfm@altlinux.org> Acked-by: Aleksa Sarai <asarai@suse.de> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
