The data ready interrupt is only enabled for the triggered buffer when DMA is not in use and the device's own trigger is in use, see at91_adc_buffer_check_use_irq(). The DMA completion callback still polls indio_dev->trig as it must run the pollfunc on whichever trigger the device is using. This removes one dependency on the trig field of struct iio_dev, which is to become private to the IIO core.
