From 468577abe37ff7b453a9ac613e0ea155349203ae Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 15 Nov 2007 12:08:45 +0800 Subject: [PATCH] [CRYPTO] scatterwalk: Use generic scatterlist chaining This patch converts the crypto scatterwalk code to use the generic scatterlist chaining rather the version specific to crypto.
