From 99a7ffffd5e85bb1e079752be51b67d5257b6a87 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Mon, 19 Sep 2016 18:22:12 +0300 Subject: [PATCH] crypto: omap-sham - add context export/import stubs Initially these just return -ENOTSUPP to indicate that they don't really do anything yet. Some sort of implementation is required for the driver to at least probe.
