[ Upstream commit 9b80bdb10aee04ce7289896e6bdad13e33972636 ]
Remove a surplus return statement from the void function that has been added in the commit commit 8353813c88ef ("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; +}
