From b074b601efbaadc829e4dd49163949f16f4ce194 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Thu, 8 Oct 2020 09:34:56 +0000 Subject: crypto: talitos - Fix return type of current_desc_hdr() [ Upstream commit 0237616173fd363a54bd272aa3bd376faa1d7caa ] current_desc_hdr() returns a u32 but in fact this is a __be32, leading to a lot of sparse warnings. Change the return type to __be32 and ensure it is handled as sure by the caller.
