[PATCH v2 4/8] iio: inkern: return valid type on raw to processed conversion

From: Liam Beguin
Date: Mon Jun 07 2021 - 10:48:51 EST


From: Liam Beguin <lvb@xxxxxxxxxx>

iio_convert_raw_to_processed_unlocked() applies the offset and scale of
a channel on it's raw value.
The processed value returned is always an integer. Return IIO_VAL_INT so
that consumers can use this return value directly.
