This patch incurs below build warning,
drivers/gpu/drm/exynos/exynos_drm_gem.c: In function
'exynos_drm_gem_prime_import_sg_table':
drivers/gpu/drm/exynos/exynos_drm_gem.c:670:3: warning: return from
incompatible pointer type [enabled by default]
We can simply return ERR_PTR(ret) and I just fixed it.
