From b973eaab68db858cb42f5283b1b0ed6773d8fdd9 Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Wed, 22 Jun 2016 16:23:36 +0300 Subject: [PATCH] crypto: omap - do not call dmaengine_terminate_all The extra call to dmaengine_terminate_all is not needed, as the DMA is not running at this point. This improves performance slightly.
