From 28cf86fafdd663cfcad3c5a5fe9869f1fa01b472 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 12 Jul 2016 13:17:58 +0800 Subject: crypto: scatterwalk - Remove unnecessary advance in scatterwalk_pagedone The offset advance in scatterwalk_pagedone not only is unnecessary, but it was also buggy when it was needed by scatterwalk_copychunks. As the latter has long ago been fixed to call scatterwalk_advance directly, we can remove this unnecessary offset adjustment.
