Subject[PATCH v2] crypto: caam: blob_gen.c: fix CAAM io mem access
Date
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: 6a83830f649a ("crypto: caam - warn if blob_gen key is insecure")
Signed-off-by: Nikolaus Voss <nikolaus.voss@haag-streit.com>
