From 581dc2ccb1a801cb8b56a2d29e3346add7998200 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Mon, 17 Nov 2014 14:42:39 +0100 Subject: [PATCH] dmaengine: mv_xor: Remove device_control The Marvell XOR engine doesn't allow any operations that use to be defined in device_control, it shouldn't need to be defined. Since it's going to be deprecated, remove it altogether.
