Narcisa Ana Maria Vasile 8f114acd4e iio: chemical: ccs811: Fix output of IIO_CONCENTRATION channels ... in_concentration_raw should report, according to sysfs-bus-iio documentation, a "Raw (unscaled no offset etc.) percentage reading of a substance." Modify scale to convert from ppm/ppb to percentage: 1 ppm = 0.0001% 1 ppb = 0.0000001% There is no offset needed to convert the ppm/ppb to percentage, so remove offset from IIO_CONCENTRATION (IIO_MOD_CO2) channel. Cc'd stable to reduce chance of userspace breakage in the long run as we fix this wrong bit of ABI usage.
