From d6f0c3d3a815aca40f1ea9daf6ed0d1f9e243185 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Fri, 2 Oct 2015 11:21:12 -0700 Subject: [PATCH] Input: cyttsp - use PTR_ERR_OR_ZERO() The PTR_ERR_OR_ZERO() helper function checks if a pointer contains an errno code and returns it or return 0 if that's not the case. Use the helper instead of open coding the same logic in the driver. This was found with make coccicheck that complains with the following warning: drivers/input/touchscreen/cyttsp4_i2c.c:53:1-3: WARNING: PTR_ERR_OR_ZERO can be used Signed-off-by: Javier Martinez Canillas Signed-off-by: Dmitry Torokhov --- drivers/input/touchscreen/cyttsp4_i2c.c | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) diff --git a/drivers/input/touchscreen/cyttsp4_i2c.c b/drivers/input/touchscreen/cyttsp4_i2c.c index a9f95c7d3c00..564e49002d5d 100644 --- a/drivers/input/touchscreen/cyttsp4_i2c.c +++ b/drivers/input/touchscreen/cyttsp4_i2c.c @@ -50,10 +50,7 @@ static int cyttsp4_i2c_probe(struct i2c_client *client, ts = cyttsp4_probe(&cyttsp4_i2c_bus_ops, &client->dev, client->irq, CYTTSP4_I2C_DATA_SIZE); - if (IS_ERR(ts)) - return PTR_ERR(ts); - - return 0; + return PTR_ERR_OR_ZERO(ts); } static int cyttsp4_i2c_remove(struct i2c_client *client) -- 2.20.1
