Linux kernel source tree
dce9414284
icosq_str size is unnecessarily too long, and it causes a build warning
-Wformat-truncation with W=1. Looking closely, It doesn't need to be 255B,
hence this patch reduces the size to 32B which should be more than enough
to host the string: "ICOSQ: 0x%x, ".
While here, add a missing space in the formatted string.
This fixes the following build warning:
$ KCFLAGS='-Wall -Werror'
$ make O=/tmp/kbuild/linux W=1 -s -j12 drivers/net/ethernet/mellanox/mlx5/core/

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.
