From mboxrd@z Thu Jan 1 00:00:00 1970 From: Javier Martinez Canillas Subject: [PATCH 18/18] Input: tps6507x-ts - simplify function return logic Date: Fri, 2 Oct 2015 15:40:29 +0200 Message-ID: <1443793229-22363-19-git-send-email-javier@osg.samsung.com> References: <1443793229-22363-1-git-send-email-javier@osg.samsung.com> Return-path: In-Reply-To: <1443793229-22363-1-git-send-email-javier@osg.samsung.com> Sender: linux-kernel-owner@vger.kernel.org To: linux-kernel@vger.kernel.org Cc: Javier Martinez Canillas , Dmitry Torokhov , Wolfram Sang , linux-input@vger.kernel.org List-Id: linux-input@vger.kernel.org The invoked function already returns zero on success or a negative errno code so there is no need to open code the logic in the caller. This also fixes the following make coccicheck warning: drivers/input/touchscreen/tps6507x-ts.c:57:5-8: WARNING: end returns can be simplified Signed-off-by: Javier Martinez Canillas --- drivers/input/touchscreen/tps6507x-ts.c | 9 +-------- 1 file changed, 1 insertion(+), 8 deletions(-) diff --git a/drivers/input/touchscreen/tps6507x-ts.c b/drivers/input/touchscreen/tps6507x-ts.c index 4ffd829d1990..a340bfccdfb6 100644 --- a/drivers/input/touchscreen/tps6507x-ts.c +++ b/drivers/input/touchscreen/tps6507x-ts.c @@ -50,14 +50,7 @@ struct tps6507x_ts { static int tps6507x_read_u8(struct tps6507x_ts *tsc, u8 reg, u8 *data) { - int err; - - err = tsc->mfd->read_dev(tsc->mfd, reg, 1, data); - - if (err) - return err; - - return 0; + return tsc->mfd->read_dev(tsc->mfd, reg, 1, data); } static int tps6507x_write_u8(struct tps6507x_ts *tsc, u8 reg, u8 data) -- 2.4.3
