From: Srinivas Pandruvada <srinivas.pandruvada@xxxxxxxxxxxxxxx> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit 0b4dce2ee694a991ef38203ec5ff91a738518cb3 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.
