In pci_epf_test_print_rate(), instead of open coding a reduction loop to allow for a division by a 32-bits ns value, simply use div64_u64() to calculate the transfer rate. To match the printed unit of KB/s, this calculation divides the rate by 1000 instead of 1024 (that would be KiB/s unit). Change the format of the results printed by pci_epf_test_print_rate() to be more compact without the double new line. Also use dev_info() instead of pr_info().

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.
