drm/rockchip: don't leak iommu mapping arm_iommu_attach_device() takes its own reference to the mapping we give it. Since we do not keep a reference to the mapping ourselves, we must release it before returning. Also fix the error path, which fails to release the mapping if it has called arm_iommu_detach_device() since that clears archdata.mapping. Signed-off-by: John Keeping <john@metanate.com>
