Subject: [PATCH 4.7 074/184] iio: humidity: am2315: set up buffer timestamps for non-zero values

4.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alison Schofield <amsfield22@...il.com>

commit 3c68858df7c2f0c4c343bb4702733fe827491f9e upstream.

Use the iio_pollfunc_store_time parameter during triggered buffer
set-up to get valid timestamps.
