Arnd Bergmann 6509f30962 tty: hide unused pty_get_peer function
TIOCGPTPEER is only used for unix98 PTYs, and we get a warning
when those are disabled:

drivers/tty/pty.c:466:12: error: 'pty_get_peer' defined but not used [-Werror=unused-function]

This moves the respective functions inside of the existing #ifdef.

Fixes: 54ebbfb160 ("tty: add TIOCGPTPEER ioctl")

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
