From 8addf571aeb7ef096201315737543b4c5303300a Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Mon, 19 Sep 2016 18:22:14 +0300 Subject: [PATCH] crypto: omap-sham - rename sgl to sgl_tmp for deprecation The current usage of sgl will be deprecated, and will be replaced by an array required by the sg based driver implementation. Rename the existing variable as sgl_tmp so that it can be removed from the driver easily later.
