Subject[PATCH v3 5/8] iio: common: cros_ec_sensors: use core structure
Date
Drivers based on cros_ec_sensors_core have structure containing the
core structure. In order to simplify, we drop all the specific and
useless structure to use the same one in all drivers.
If a future driver need specific field, we can add a private pointer
to that data.
