Make the conversion clearly visible by using an explicit cast. This also avoids a warning seen with clang: drivers/iio/adc/max9611.c:292:16: warning: implicit conversion from enumeration type 'enum max9611_conf_ids' to different enumeration type 'enum max9611_csa_gain' [-Wenum-conversion] *csa_gain = gain_selectors[i]; ~ ^~~~~~~~~~~~~~~~~ Signed-off-by: Stefan Agner --- drivers/iio/adc/max9611.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/iio/adc/max9611.c b/drivers/iio/adc/max9611.c index 0538ff8c4ac1..643a4e66eb80 100644 --- a/drivers/iio/adc/max9611.c +++ b/drivers/iio/adc/max9611.c @@ -289,7 +289,7 @@ static int max9611_read_csa_voltage(struct max9611_dev *max9611, return ret; if (*adc_raw > 0) { - *csa_gain = gain_selectors[i]; + *csa_gain = (enum max9611_csa_gain)gain_selectors[i]; return 0; } } -- 2.18.0
