From: Michael Hennerich <michael.hennerich@xxxxxxxxxx> Not sure if this is a proper fix. However it should do the trick. ring->scan_maks is allocated in iio_ring_buffer_register() which called after adis16400_configure_ring. So the time this pointer dereference takes place scan_mask is uninitialized.
