If anyone has any objections, please let me know. ------------------ From: Srinivas Pandruvada <srinivas.pandruvada@...ux.intel.com> commit 0668a4e4d297328ce08b44d91d160537596115e2 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.
