Jonathan Cameron a9c2ffa21e iio: accel: sca3000: Fix alignment for DMA safety
[ Upstream commit a263456f0e ]

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

The second alignment marking is left in place to avoid doing more than
the simple fix in this patch.

Fixes: ced5c03d36 ("staging:iio:accel:sca3000 merge files into one.")
Fixes: 152a6a884a ("staging:iio:accel:sca3000 move to hybrid hard / soft buffer design.")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
