From 4f8ef9f4140cc286d7d1cf9237da7a7439e4fc0b Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Mon, 17 Nov 2014 14:42:03 +0100 Subject: [PATCH] dmaengine: Remove the need to declare device_control In order to migrate the drivers without triggering a BUG_ON for the converted drivers, which would cause bisectability issues, we need to remove that check before removing the device_control function entirely.
