[PATCH v2 14/20] iio: temperature: Use iio_push_to_buffers_with_ts() to provide length for runtime checks.

[Jonathan Cameron <jic23@kernel.org>]

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

This new function allows us to perform debug checks in the helper to ensure
that the overrun does not occur.  Use it in all the simple cases where
either a static buffer or a structure is used in the drivers.
