The ATTRIBUTE_GROUP(bmi323_event) macro will define two variables,
bmi323_event_groups and bmi323_event_group. The event_attrs member
of iio_info is of type struct attribute_group*, which means that
bmi323_event_groups will remain unused. Since I am using a single
event group, Can I keep it the same way?
