From: Paul Mundt <lethal@xxxxxxxxxxxx> Both the max1363 and lis3l02dq modules rely on IIO trigger support in their ring buffer implementations, which is presently a separate config option. In the case of IIO_RING_BUFFER=y and IIO_TRIGGER=n, we end up with the following: ERROR: "iio_trigger_attach_poll_func" [drivers/staging/iio/adc/max1363.ko] undefined! ERROR: "iio_trigger_dettach_poll_func" [drivers/staging/iio/adc/max1363.ko] undefined! ERROR: "iio_trigger_unregister" [drivers/staging/iio/accel/lis3l02dq.ko] undefined!
