Subject: [PATCH 7/9] crypto: sun8i-ce: increase task list size
Date: Wed, 22 Jan 2020 11:45:26 +0100	[thread overview]
Message-ID: <20200122104528.30084-8-clabbe.montjoie@gmail.com> (raw)
In-Reply-To: <20200122104528.30084-1-clabbe.montjoie@gmail.com>

The CE can handle more than 1 task at once, so this patch increase the size of
the task list up to 8.
For the moment I did not see more gain beyong this value.
