> 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.
