Subject: crypto: caam - change return value in case CAAM has no MDHA
Git-commit: 0435d47e2627b76b6dfb59e2e95ffed7232bd0ed
Patch-mainline: v5.4-rc1
References: jsc#SLE-16106
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.
