Russell King (Oracle) ac9a8587ed net: stmmac: "speed" passed to fix_mac_speed is an int
priv->plat->fix_mac_speed() is called from stmmac_mac_link_up(), which
is passed the speed as an "int". However, fix_mac_speed() implicitly
casts this to an unsigned int. Some platform glue code print this value
using %u, others with %d. Some implicitly cast it back to an int, and
others to u32.

Good practice is to use one type and only one type to represent a value
being passed around a driver.

Switch all of these over to consistently use "int" when dealing with a
speed passed from stmmac_mac_link_up(), even though the speed will
always be positive.

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 reStructuredText 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.
