SRU justification:
Problem: If the heartbeat function is assigned to a led via a device tree, the led instead of beating is turned off, and in case of a headless system, the board seems to be dead.
Fix: Apply the attached patch and recompile
How to reproduce: Assign the heartbeat trigger to a user configurable led and check if it beats:
echo heartbeat > /sys/class/leds/$LED/trigger

The beaglebone black has a led that blinks like a heartbeat. But it is not working with the snappy image because the ledtrig-heartbeat is not loaded.
When I do:
sudo modprobe ledtrig-heartbeat
it starts to blink.
Please make the ledtrig-heartbeat a build-in option so when we install snappy in the bbb it blinks.
