Subject: [PATCH 5/9] drm: export drm_vm_open_locked

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!
