From 6c49d79381f4bacacdef50a1902c92833e765c63 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 29 Dec 2013 19:47:18 -0300 Subject: [PATCH] [media] ec168: fix error return code The rest of the function uses ret to store the return value, even setting ret to i a few lines before this, so return ret instead of i. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // Signed-off-by: Julia Lawall Cc: Antti Palosaari Signed-off-by: Mauro Carvalho Chehab --- drivers/media/usb/dvb-usb-v2/ec168.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/media/usb/dvb-usb-v2/ec168.c b/drivers/media/usb/dvb-usb-v2/ec168.c index 5c68f3918bc8..0c2b377704ff 100644 --- a/drivers/media/usb/dvb-usb-v2/ec168.c +++ b/drivers/media/usb/dvb-usb-v2/ec168.c @@ -170,7 +170,7 @@ static int ec168_i2c_xfer(struct i2c_adapter *adap, struct i2c_msg msg[], error: mutex_unlock(&d->i2c_mutex); - return i; + return ret; } static u32 ec168_i2c_func(struct i2c_adapter *adapter) -- 2.20.1
