Jonathan et all, Has anyone noticed that there is no clear consensus on which error code to return when a i2c_check_functionality() check fails within the probe function. I've seen so far ENODEV, ENOTSUPP, EOPNOTSUPP, EIO, and ENOSYS in drivers/iio Shouldn't these be made a standard value like -ENOTSUPP?
