Subject: crypto: caam/qi - abort algorithm setup on DPAA2 parts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Git-commit: d3b5a87c4a8178b34b93a463870eca549a103aee
Patch-mainline: v4.15-rc1
References: fate#326534

caam/qi frontend (i.e. caamalg_qi) mustn't be used in case it runs on a
DPAA2 part (this could happen when using a multiplatform kernel).

Fixes: 297b9cebd2fc ("crypto: caam/jr - add support for DPAA2 parts")
