[ Upstream commit 9b80bdb10aee04ce7289896e6bdad13e33972636 ]
Remove a surplus return statement from the void function that has been
added in the commit commit 8353813c88 ("PCI: endpoint: Enable DMA
tests for endpoints with DMA capabilities").
Especially, as an empty return statements at the end of a void functions
serve little purpose.
This fixes the following checkpatch.pl script warning:
WARNING: void function return statements are not generally useful
#296: FILE: drivers/pci/endpoint/functions/pci-epf-test.c:296:
+ return;
+}

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.
