From aa1ac27f48de0ed94d5a104e15b5ab62b5deb236 Mon Sep 17 00:00:00 2001 From: John Keeping Date: Tue, 5 Apr 2016 14:50:31 +0100 Subject: [PATCH] drm/rockchip: remove redundant statement The call to arm_iommu_detach_device() on the previous line sets dev->archdata.mapping to NULL so this call is always a no-op.
