Subject: [PATCH] crypto: caam: blob_gen.c: fix CAAM io mem access
Message-Id: <20221205075839.050FF27BD@mail.steuer-voss.de>
Date:   Mon,  5 Dec 2022 08:58:39 +0100 (CET)
Precedence: bulk

IO memory access has to be done with accessors defined in caam/regs.h
as there are little-endian architectures with a big-endian CAAM unit.

Fixes ("crypto: caam: blob_gen.c: warn if key is insecure")
