From: Julia Lawall <Julia.Lawall@xxxxxxx> Convert a zero return value on error to a negative one, as returned elsewhere in the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- drivers/mfd/twl6040.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/mfd/twl6040.c b/drivers/mfd/twl6040.c index f9c06c5..9687645 100644 --- a/drivers/mfd/twl6040.c +++ b/drivers/mfd/twl6040.c @@ -679,6 +679,7 @@ static int twl6040_probe(struct i2c_client *client, if (twl6040->rev < 0) { dev_err(&client->dev, "Failed to read revision register: %d\n", twl6040->rev); + ret = twl6040->rev; goto gpio_err; } -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
