Title:
  heartbeat module is not loaded

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Wily:
  Fix Committed

Bug description:
  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.
