[PATCH 14/14] crypto: caam - change return value in case CAAM has no MDHA

From: Iuliana Prodan
Date: Thu Jul 18 2019 - 10:46:00 EST


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.
