[PATCH 5.18 0588/1095] iio: accel: adxl355: Fix alignment for DMA safety

[Greg Kroah-Hartman]

From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>

[ Upstream commit 46403dcf3a7cbd24b86f809fd79962f4d6b137c5 ]

 ____cacheline_aligned is insufficient guarantee for non-coherent DMA.
Switch to the updated IIO_DMA_MINALIGN definition.

Fixes: 327a0eaf19d53 ("iio: accel: adxl355: Add triggered buffer support")
