Subject: hwmon: (ntc_thermistor) Ensure iio channel is of type IIO_VOLTAGE
From: Chris Lesiak <[email protected]>
commit adba657533bdd255f7b78bc8a324091f46b294cd upstream.
When configured via device tree, the associated iio device needs to be measuring voltage for the conversion to resistance to be correct. Return -EINVAL if that is not the case.
