iio: inkern: fix iio_convert_raw_to_processed_unlocked commit f91d1b63a4e096d3023aaaafec9d9d3aff25997f upstream. When reading IIO_CHAN_INFO_OFFSET, the return value of iio_channel_read() for success will be IIO_VAL*, checking for 0 is not correct. Without this fix the offset applied by iio drivers will be ignored when converting a raw value to one in appropriate base units (e.g mV) in a IIO client drivers that use iio_convert_raw_to_processed including iio-hwmon.
