vrahane opened a new pull request #718: MYNEWT-881 SensorAPI: LIS2DH12 set thresh cb fix
URL: https://github.com/apache/mynewt-core/pull/718
 
 
   There are two issues for calling lis2dh12_sensor_set_trigger_thresh() multiple times:
   
   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.
