drm/exynos: Properly propagate return value in drm_iommu_attach_device()
Propagate the proper error codes from the called functions instead of unconditionally returning 0. Reported-by: kbuild test robot <lkp@intel.com> Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Merge conflict so merged it manually. Signed-off-by: Inki Dae <inki.dae@samsung.com>
