From: John Keeping Date: Tue, 5 Apr 2016 13:50:31 +0000 (+0100) Subject: drm/rockchip: remove redundant statement X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=aa1ac27f48de0ed94d5a104e15b5ab62b5deb236;p=openwrt%2Fstaging%2Fblogic.git 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.
