From d6f25bd9d4079165ea90f12d71e06d1dca83cd86 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 9 Jul 2019 21:08:48 +0900 Subject: drm/exynos: add CONFIG_MMU dependency Compile-testing this driver on a NOMMU configuration shows a link failure: drivers/gpu/drm/exynos/exynos_drm_gem.o: In function `exynos_drm_gem_fault': exynos_drm_gem.c:(.text+0x484): undefined reference to `vmf_insert_mixed' Add a CONFIG_MMU dependency to ensure we only enable this in configurations that build correctly. Many other drm drivers have the same dependency. It would be nice to make this work in MMU-less configurations, but evidently nobody has ever needed this so far.
