The exynos DRM module currently is not automatically loaded when build as a module. This is due to the simple fact that it doesn't have any MODULE_DEVICE_TABLE entries whatsoever... Most of these were removed previously as it wasn't possible at the time to have multiple calls to MODULE_DEVICE_TABLE in one module, however commit 21bdd17b21b45ea solved that.
The first two patches revert the previous removals of MODULE_DEVICE_TABLE calls, while the last one adds calls for the remaining OF match tables without a MODULE_DEVICE_TABLE call.
Sjoerd Simons (3): Revert "drm/exynos: fix module build error" Revert "drm/exynos: remove MODULE_DEVICE_TABLE definitions" drm/exynos: Add MODULE_DEVICE_TABLE entries for various components
