Subject: [PATCH 3/8] Bluetooth: Rename smp_key_size to enc_key_size
Date: Tue, 6 Dec 2011 21:48:07 -0300 [thread overview]
Message-ID: <1323218892-15785-4-git-send-email-vinicius.gomes@openbossa.org> (raw)
In-Reply-To: <1323218892-15785-1-git-send-email-vinicius.gomes@openbossa.org>
This makes clear that this is the size of the key used to
encrypt the link.
