The event_attrs field of iio_info structure is only initialized once
whenever an object of iio_info is created. After that this field
is never modified again anywhere in the kernel. So, declare event_attrs
field of iio_info as a const struct attribute_group.
Checked for occurences throughout the kernel using grep and
coccinelle.
