Fixes tag is inaccurate but prior to that likely manual backporting needed (for anything before 4.18) Earlier than that the include file to fix is drivers/iio/common/cros_ec_sensors/cros_ec_sensors_core.h: commit 974e6f02e27 ("iio: cros_ec_sensors_core: Add common functions for the ChromeOS EC Sensor Hub.") present since kernel stable 4.10.
