Andrey Vatoropin c4e068ad25 hwmon: (xgene-hwmon) use appropriate type for the latency value
[ Upstream commit 8df0f002827e18632dcd986f7546c1abf1953a6f ]

The expression PCC_NUM_RETRIES * pcc_chan->latency is currently being
evaluated using 32-bit arithmetic.

Since a value of type 'u64' is used to store the eventual result,
and this result is later sent to the function usecs_to_jiffies with
input parameter unsigned int, the current data type is too wide to
store the value of ctx->usecs_lat.

Change the data type of "usecs_lat" to a more suitable (narrower) type.

README

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.
