It seems ad7797_attribute_group should be used in ad7797_info,
according to commit ("iio:ad7793: Add support for the ad7796 and ad7797").
While the change looks good at first, I am thinking that this might introduce
another issue while fixing this one.
It looks like the ad7797_attributes[] array may also require the
&iio_dev_attr_in_m_in_scale_available.dev_attr.attr attribute as well.
It looks like the available scales should be printed for AD7997 as well.
That being said, this patch is fine as-is.
But it would require a patch [before-this-patch] to fix the ad7797_attributes
array.
Something like this:
static struct attribute *ad7797_attributes[] = {
&iio_const_attr_sampling_frequency_available_ad7797.dev_attr.attr,
+ &iio_dev_attr_in_m_in_scale_available.dev_attr.attr,
NULL
};
I'm hoping I'm right about this one. I sometimes don't notice things too well.
Scale is fixed for the ad7796 and not programmable. Usually we only have
the scale attribute itself in that case and no scale_available attribute.
