This is adding a new warning:

	$ ./scripts/get_abi.pl validate
	Warning: file Documentation/ABI/testing/sysfs-class-firmware-attributes#172:
		What '/sys/class/firmware-attributes/*/authentication/' doesn't have a description

Because you forgot to add a Description: tag.

Feel free to either add the enclosed tag to the tree which added this into
linux-next, or to fold id with the original patch.

Thanks,
Mauro

ABI: docs: sysfs-class-firmware-attributes: add a missing tag
