Vipul Rahane updated MYNEWT-881:
--------------------------------
Description:
There are two issues for calling the `lis2dh12_sensor_set_trigger_thresh()`:
1. gpio irq was not being released before doing a re-initialization
2. srec was malloced and calling the function multiple times would have
malloced additional memory without freeing it.
Solution:
1. Release the gpio irq
2. Remove the malloc and add a ptr for the sensor in each type trait so that a
sensor read could be performed in the irq handler.
Also, `sensor_unset_thresh()` API was added to unset thresholds
triggers/interrupts.
