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: 54ebbfb1 ("tty: add TIOCGPTPEER ioctl")
...
-#define TIOCGPTPEER	_IOR('T', 0x41, int) /* Safely open the slave */
+#define TIOCGPTPEER	_IO('T', 0x41) /* Safely open the slave */

This is a user API change. When was the ioctl added?

It was just pulled this merge window (4.13-rc1).
