Subject: iio: hid_sensor_hub: Fix indio_dev->trig assignment
From: Srinivas Pandruvada <srinivas.pandruvada@xxxxxxxxxxxxxxx>
commit 55a6f9ddfdea0d2d343cd1b39baf8aa752664b6e 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.
