From 2097aa410e0d8541cee7ce0b28bb9ac681722e10 Mon Sep 17 00:00:00 2001 From: John Keeping Date: Tue, 5 Apr 2016 14:50:31 +0100 Subject: [PATCH] UPSTREAM: 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.
