From 147e45d9210ce303eb8a3a3c6593631ff78cd072 Mon Sep 17 00:00:00 2001 From: Roberta Dobrescu Date: Sun, 26 Oct 2014 23:30:07 +0200 Subject: [PATCH] staging: rtl8723au: hal: Remove uneeded return variable This patch removes uneeded return variables, just using 'return _SUCCESS' or 'return HCI_STATUS_SUCCESS' instead. This fixes the following warning detected using coccinelle: Unneeded variable. It was done using the following semantic patch: @@ identifier ret; type T; expression e; @@ -T ret = e; ... when != ret when strict -return ret; +return e; Signed-off-by: Roberta Dobrescu Signed-off-by: Greg Kroah-Hartman --- .../staging/rtl8723au/hal/rtl8723a_bt-coexist.c | 17 +++++------------ drivers/staging/rtl8723au/hal/rtl8723a_cmd.c | 7 ++----- .../staging/rtl8723au/hal/rtl8723a_hal_init.c | 14 ++++---------- drivers/staging/rtl8723au/hal/rtl8723a_phycfg.c | 3 +-- 4 files changed, 12 insertions(+), 29 deletions(-) diff --git a/drivers/staging/rtl8723au/hal/rtl8723a_bt-coexist.c b/drivers/staging/rtl8723au/hal/rtl8723a_bt-coexist.c index 9054a987f06b..5de806e45c3b 100644 --- a/drivers/staging/rtl8723au/hal/rtl8723a_bt-coexist.c +++ b/drivers/staging/rtl8723au/hal/rtl8723a_bt-coexist.c @@ -1766,9 +1766,7 @@ bthci_CmdSetEventFilter( struct packet_irp_hcicmd_data *pHciCmd ) { - enum hci_status status = HCI_STATUS_SUCCESS;
