[PATCH 6.12.y 2/2] iio: light: as73211: Ensure buffer holes are zeroed

[Sasha Levin <sashal@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

[ Upstream commit 433b99e922943efdfd62b9a8e3ad1604838181f2 ]

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