Arnd Bergmann 73066f6c53 net: niu: fix format string overflow warning:
We get a warning for the port_name string that might be longer than
six characters if we had more than 10 ports:

drivers/net/ethernet/sun/niu.c: In function 'niu_put_parent':
drivers/net/ethernet/sun/niu.c:9563:21: error: '%d' directive writing between 1 and 3 bytes into a region of size 2 [-Werror=format-overflow=]
  sprintf(port_name, "port%d", port);
                     ^~~~~~~~
drivers/net/ethernet/sun/niu.c:9563:21: note: directive argument in the range [0, 255]
drivers/net/ethernet/sun/niu.c:9563:2: note: 'sprintf' output between 6 and 8 bytes into a destination of size 6
  sprintf(port_name, "port%d", port);
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/ethernet/sun/niu.c: In function 'niu_pci_init_one':
drivers/net/ethernet/sun/niu.c:9538:22: error: '%d' directive writing between 1 and 3 bytes into a region of size 2 [-Werror=format-overflow=]
   sprintf(port_name, "port%d", port);
                      ^~~~~~~~
drivers/net/ethernet/sun/niu.c:9538:22: note: directive argument in the range [0, 255]
drivers/net/ethernet/sun/niu.c:9538:3: note: 'sprintf' output between 6 and 8 bytes into a destination of size 6

While we know that the port number is small, there is no harm in
making the format string two bytes longer to avoid the warning.

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.
