From 9b17e5ad7831cde78314f96445cfb4a9945c6c68 Mon Sep 17 00:00:00 2001 From: Corentin LABBE Date: Wed, 10 Aug 2016 11:45:33 +0200 Subject: [PATCH] crypto: sun4i-ss - Always use sun4i_tfm_ctx for storing pointer to dev ss The dev *ss is stored both in sun4i_tfm_ctx and sun4i_req_ctx. Since this pointer will never be changed during tfm life, it is better to remove it from sun4i_req_ctx.
