From 00e4d3e845e3f8bea8ef4ebe35499ba44cacacb4 Mon Sep 17 00:00:00 2001 From: Eneas U de Queiroz Date: Fri, 20 Sep 2019 17:48:04 -0300 Subject: [PATCH] ipq40xx: fix hw-crypto detection of qce driver This adds the CRYPTO_ALG_KERN_DRIVER_ONLY flag to Qualcomm crypto engine driver algorithms, so that openssl devcrypto can recognize them as hardware-accelerated.
