If anyone has any objections, please let me know. ------------------ From: Wang Jiang [ 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; +} Link: https://lore.kernel.org/r/tencent_F250BEE2A65745A524E2EFE70CF615CA8F06@qq.com Signed-off-by: Wang Jiang [kwilczynski: commit log] Signed-off-by: Krzysztof Wilczyński Stable-dep-of: 85afa9ea122d ("PCI: endpoint: pci-epf-test: Add NULL check for DMA channels before release") Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman --- drivers/pci/endpoint/functions/pci-epf-test.c | 2 -- 1 file changed, 2 deletions(-) --- a/drivers/pci/endpoint/functions/pci-epf-test.c +++ b/drivers/pci/endpoint/functions/pci-epf-test.c @@ -291,8 +291,6 @@ static void pci_epf_test_clean_dma_chan( dma_release_channel(epf_test->dma_chan_rx); epf_test->dma_chan_rx = NULL; - - return; } static void pci_epf_test_print_rate(const char *ops, u64 size,
