Subject: [PATCH] iio: light: as73211: Ensure buffer holes are zeroed

Given that the buffer is copied to a kfifo that ultimately user space
can read, ensure we zero it.

[ Upstream commit a801016da0bbb955acf1a551584790e3816bb4db ]

Use this new type to both slightly simplify the code and avoid
confusing static analysis tools. Mostly this series is about consistency
to avoid this code pattern getting copied into more drivers.
