Subject: [PATCH 3.16 220/357] iio:trigger: modify return value for iio_trigger_get

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

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

From: Srinivas Pandruvada <srinivas.pandruvada@...ux.intel.com>

commit f153566570fb9e32c2f59182883f4f66048788fb upstream.

Instead of a void function, return the trigger pointer.

Whilst not in of itself a fix, this makes the following set of
7 fixes cleaner than they would otherwise be.
