From f6d706dd9baaa1d7857ce5b03af491718a95e9bf Mon Sep 17 00:00:00 2001 From: Yang Li Date: Wed, 10 Mar 2021 17:00:34 +0800 Subject: char/mwave: turn tp3780I_Cleanup() into void function This function always return '0' and no callers use the return value. So make it a void function. This eliminates the following coccicheck warning: ./drivers/char/mwave/tp3780i.c:182:5-11: Unneeded variable: "retval". Return "0" on line 187 Reported-by: Abaci Robot Signed-off-by: Yang Li Link: https://lore.kernel.org/r/1615366834-20545-1-git-send-email-yang.lee@linux.alibaba.com Signed-off-by: Greg Kroah-Hartman --- drivers/char/mwave/tp3780i.c | 6 +----- drivers/char/mwave/tp3780i.h | 2 +- 2 files changed, 2 insertions(+), 6 deletions(-) (limited to 'drivers') diff --git a/drivers/char/mwave/tp3780i.c b/drivers/char/mwave/tp3780i.c index 5e1618a76b2a..8588b51202e5 100644 --- a/drivers/char/mwave/tp3780i.c +++ b/drivers/char/mwave/tp3780i.c @@ -177,14 +177,10 @@ int tp3780I_InitializeBoardData(THINKPAD_BD_DATA * pBDData) return retval; } -int tp3780I_Cleanup(THINKPAD_BD_DATA * pBDData) +void tp3780I_Cleanup(THINKPAD_BD_DATA *pBDData) { - int retval = 0; - PRINTK_2(TRACE_TP3780I, "tp3780i::tp3780I_Cleanup entry and exit pBDData %p\n", pBDData); - - return retval; } int tp3780I_CalcResources(THINKPAD_BD_DATA * pBDData) diff --git a/drivers/char/mwave/tp3780i.h b/drivers/char/mwave/tp3780i.h index 07685b68538f..8bd976d42fae 100644 --- a/drivers/char/mwave/tp3780i.h +++ b/drivers/char/mwave/tp3780i.h @@ -91,7 +91,7 @@ int tp3780I_DisableDSP(THINKPAD_BD_DATA * pBDData); int tp3780I_ResetDSP(THINKPAD_BD_DATA * pBDData); int tp3780I_StartDSP(THINKPAD_BD_DATA * pBDData); int tp3780I_QueryAbilities(THINKPAD_BD_DATA * pBDData, MW_ABILITIES * pAbilities); -int tp3780I_Cleanup(THINKPAD_BD_DATA * pBDData); +void tp3780I_Cleanup(THINKPAD_BD_DATA *pBDData); int tp3780I_ReadWriteDspDStore(THINKPAD_BD_DATA * pBDData, unsigned int uOpcode, void __user *pvBuffer, unsigned int uCount, unsigned long ulDSPAddr); -- cgit v1.2.3
