drm: move module initialization to drm_stub.c
Most of the new DRM management functions are nowadays in drm_stub.c. By moving the core module initialization to drm_stub.c we can make several global variables static and keep the stub-open helper local. The core files now look like this: drm_stub.c: Core management drm_drv.c: Ioctl dispatcher drm_ioctl.c: Actual ioctl backends drm_fops.c: Char-dev file-operations A follow-up patch will move what is left from drm_drv.c into drm_ioctl.c. Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: David Herrmann <dh.herrmann@gmail.com>
