Hello,
> Correctly initialize device channels, otherwise writing the calibration
> values to sysfs nodes does not work
I think the fix should rather be
if (chan->channel2 == IIO_MOD_LIGHT_BOTH)
chip->calib0 = calib_from_sysfs(val);
else if (chan->channel2 == IIO_MOD_LIGHT_IR)
chip->calib1 = calib_from_sysfs(val);
else
return -EINVAL;
since only the INTENSITY channels have a CALIBSCALE info
the light channel incorrectly sets .indexed = 1 and .channel = 0 which
should be unnecessary since there is only one IIO_LIGHT channel
regards, p.
