From c41494311920c13d359ead4fb10b420d65238689 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Fri, 26 Jun 2020 16:06:06 +1000 Subject: crypto: cpt - Fix sparse warnings This patch fixes all the sparse warnings in the octeontx driver. Some of these are just trivial type changes. However, some of the changes are non-trivial on little-endian hosts. Obviously the driver appears to be broken on either LE or BE as it was doing different things. I've taken the BE behaviour as the correct one.
