Subject: [PATCH v3 01/10] crypto: marvell: Add a macro constant for the size of the crypto queue
Date: Tue, 21 Jun 2016 10:08:31 +0200	[thread overview]
Message-ID: <1466496520-28806-2-git-send-email-romain.perier@free-electrons.com> (raw)
In-Reply-To: <1466496520-28806-1-git-send-email-romain.perier@free-electrons.com>

Adding a macro constant to be used for the size of the crypto queue,
instead of using a numeric value directly. It will be easier to
maintain in case we add more than one crypto queue of the same size.
