From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>
____cacheline_aligned is an insufficient guarantee for non-coherent DMA
on platforms with 128 byte cachelines above L1. Switch to the updated
IIO_DMA_MINALIGN definition.
Fixes: 791bb52a0cd2 ("iio:ad5791: Do not store transfer buffers on the stack")
