    Subject[PATCH 5/9] drm: export drm_vm_open_locked
    Date
    Since the exynos DRM driver can now be built as a module on
    all multiplatform configurations, an existing bug has
    become visible: The exynos driver uses the drm_vm_open_locked
    function that is not exported. The obvious solution is to
    export that symbol.

    Without this patch, building ARM allmodconfig results in:

    ERROR: "drm_vm_open_locked" [drivers/gpu/drm/exynos/exynosdrm.ko] undefined!
