hid_sensor_setup_trigger() is common API used for the HID IIO drivers, prepare devm API devm_hid_sensor_setup_trigger() to acquire resource during setup and release using device managed framework during drivers fail, unbind or remove path. Register action with devm_add_action_or_reset() to release resource with devres framework.
