Subject: [PATCH v2 14/14] crypto: caam - change return value in case CAAM has no MDHA
Date: Fri, 19 Jul 2019 02:57:56 +0300	[thread overview]
Message-ID: <1563494276-3993-15-git-send-email-iuliana.prodan@nxp.com> (raw)
In-Reply-To: <1563494276-3993-1-git-send-email-iuliana.prodan@nxp.com>

To be consistent with other CAAM modules, caamhash should return 0
instead of -ENODEV in case CAAM has no MDHA.

Based on commit 1b46c90c8e00 ("crypto: caam - convert top level drivers to libraries")
the value returned by entry point is never checked and
the exit point is always executed.
