From 5506f53c7cc17c4ad5e69e5512a35faf77182986 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 12 Jul 2016 13:17:53 +0800 Subject: crypto: scatterwalk - Remove scatterwalk_bytes_sglen This patch removes the now unused scatterwalk_bytes_sglen. Anyone using this out-of-tree should switch over to sg_nents_for_len.
