David Lechner 8599dadeca iio: light: vcnl4035: fix scan buffer on big-endian 
commit fdc7aa54a5 upstream.

Rework vcnl4035_trigger_consumer_handler() so that we are not passing
what should be a u16 value as an int * to regmap_read(). This won't
work on bit endian systems.

Instead, add a new unsigned int variable to pass to regmap_read(). Then
copy that value into the buffer struct.

The buffer array is replaced with a struct since there is only one value
being read. This allows us to use the correct u16 data type and has a
side-effect of simplifying the alignment specification.

Also fix the endianness of the scan format from little-endian to CPU
endianness. Since we are using regmap to read the value, it will be
CPU-endian.

README 

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.
