[PATCH 77/92] iio: imu_icm42600: Fix alignment for DMA safety

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

 



From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>

Partial fix for this driver as a second instance was introduced in
a later patch.

____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.
