# 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.
