From e3675a4bd5f72e2551a4f4dfae7330c8b6c854dd Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Fri, 22 Aug 2014 21:48:00 +0100 Subject: [PATCH] iio: meter: ade7758: Fix indio_dev->trig assignment commit 0495081179212b758775df752e657ea71dcae020 upstream. This can result in wrong reference count for trigger device, call iio_trigger_get to increment reference. Refer to http://www.spinics.net/lists/linux-iio/msg13669.html for discussion with Jonathan.
