Date: Sun,  1 Jul 2018 22:58:05 +0900	[thread overview]
Message-ID: <1530453485-15698-1-git-send-email-minwoo.im.dev@gmail.com> (raw)

It's now currently printing the OAES(Optional Asynchronous Events Supported)
field in identify controller data structure without [9] firmware activation
notices field in case of human-readable format.
Print it out by updating the reserved bit field.
