Christophe JAILLET 8584ee20a5 IB/mlx4: Fix the size of a buffer in add_port_entries() 
commit d7f393430a17c2bfcdf805462a5aa80be4285b27 upstream.

In order to be sure that 'buff' is never truncated, its size should be
12, not 11.

When building with W=1, this fixes the following warnings:

  drivers/infiniband/hw/mlx4/sysfs.c: In function ‘add_port_entries’:
  drivers/infiniband/hw/mlx4/sysfs.c:268:34: error: ‘sprintf’ may write a terminating nul past the end of the destination [-Werror=format-overflow=]
    268 |                 sprintf(buff, "%d", i);
        |                                  ^
  drivers/infiniband/hw/mlx4/sysfs.c:268:17: note: ‘sprintf’ output between 2 and 12 bytes into a destination of size 11
    268 |                 sprintf(buff, "%d", i);
        |                 ^~~~~~~~~~~~~~~~~~~~~~

        |                                  ^

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

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

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.
