[ Upstream commit 744ec4477b11c42e2c8de9eb8364675ae7a0bd81 ]
Writing large limits resulted in overflows as reported by module tests.
in0_lcrit: Suspected overflow: [max=5538, read 0, written 2147483647]
in0_crit: Suspected overflow: [max=5538, read 0, written 2147483647]
in0_min: Suspected overflow: [max=5538, read 0, written 2147483647]
Fix the problem by clamping prior to multiplications and the use of
DIV_ROUND_CLOSEST, and by using consistent variable types.

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.
