The iio headers aren't relevant and can be removed as reported by William in [1]. With this change, mod_devicetable.h needs to be added to define the 'of_device_id' struct.

counter: Simplify the count_read and count_write callbacks 2019-10-18T18:47:27+00:00 William Breathitt Gray vilhelm.gray@gmail.com 2019-10-06T20:03:09+00:00 d49e6ee2d6c2b654c5eeb9aa1c4986cd1bec2582 The count_read and count_write callbacks are simplified to pass val as unsigned long rather than as an opaque data structure. The opaque counter_count_read_value and counter_count_write_value structures, counter_count_value_type enum, and relevant counter_count_read_value_set and counter_count_write_value_get functions, are removed as they are no longer used.
