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 <[email protected]> --- drivers/power/bq27x00_battery.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/power/bq27x00_battery.c b/drivers/power/bq27x00_battery.c index 181ddec..5860d4d 100644 --- a/drivers/power/bq27x00_battery.c +++ b/drivers/power/bq27x00_battery.c @@ -814,7 +814,8 @@ static int bq27x00_battery_probe(struct i2c_client *client, di->bat.name = name; di->bus.read = &bq27x00_read_i2c; - if (bq27x00_powersupply_init(di)) + retval = bq27x00_powersupply_init(di); + if (retval) goto batt_failed_3; i2c_set_clientdata(client, di); -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
