Yaxiong Tian 754cfada1b PM: EM: Fix incorrect description of the cost field in struct em_perf_state
[ Upstream commit 54b603f2db ]

Due to commit 1b600da510 ("PM: EM: Optimize em_cpu_energy() and remove
division"), the logic for energy consumption calculation has been modified.
The actual calculation of cost is 10 * power * max_frequency / frequency
instead of power * max_frequency / frequency.

Therefore, the comment for cost has been updated to reflect the correct
content.

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.
