Subject: [PATCH v10 05/20] crypto: marvell/cesa: remove redundant backlog checks on EBUSY
Date: Wed, 18 Oct 2017 08:00:37 +0100	[thread overview]
Message-ID: <1508310057-25369-6-git-send-email-gilad@benyossef.com> (raw)
In-Reply-To: <1508310057-25369-1-git-send-email-gilad@benyossef.com>

Now that -EBUSY return code only indicates backlog queueing
we can safely remove the now redundant check for the
CRYPTO_TFM_REQ_MAY_BACKLOG flag when -EBUSY is returned.
