When compiling with -Wformat, clang emits the following warnings:
drivers/net/ethernet/broadcom/bnx2x/bnx2x_link.c:6181:40: warning: format
specifies type 'unsigned short' but the argument has type 'u32'
(aka 'unsigned int') [-Wformat]
ret = scnprintf(str, *len, "%hx.%hx", num >> 16, num);
~~~ ^~~~~~~~~

The types of these arguments are unconditionally defined, so this patch
updates the format character to the correct ones for ints and unsigned
ints.

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.
