  # Note: When updating this revision:
  # 1. Also update pkgs/os-specific/linux/firmware/facetimehd-firmware/
  # 2. Test the module and firmware change via:
  #    a. Give some applications a try (Skype, Hangouts, Cheese, etc.)
  #    b. Run: journalctl -f
  #    c. Then close the lid
  #    d. Then open the lid (and maybe press a key to wake it up)
  #    e. see if the module loads back (apps using the camera won't
  #       recover and will have to be restarted) and the camera
  #       still works.
