[PATCH 82/92] iio: potentiometer: max5481: Fix alignment for DMA safety

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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_ALIGN definition.

Fixes: df1fd2de118e ("iio: max5481: Add support for Maxim digital potentiometers")
