iio: imu: st_lsm6dsx: check return value from st_lsm6dsx_sensor_set_enable
Add missing return value check in st_lsm6dsx_read_oneshot disabling the sensor. The issue is reported by coverity with the following error: Unchecked return value: If the function returns an error value, the error value may be mistaken for a normal value. Addresses-Coverity-ID: 1446733 ("Unchecked return value") Fixes: b5969abfa8b8 ("iio: imu: st_lsm6dsx: add motion events") Fixes: 290a6ce11d93 ("iio: imu: add support to lsm6dsx driver") Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
