PCI: endpoint: Remove surplus return statement from pci_epf_test_clean_dma_chan()
[ 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;
+}
