Many DRM drivers implement an encoder with an empty implementation. This patchset adds drm_simple_encoder_init() and drm_simple_encoder_create(), which can be used by drivers instead. Except for the destroy callback, the simple encoder's implementation is empty.
The patchset also converts 4 encoder instances to use the simple-encoder helpers. But there are at least 11 other drivers which can use the helper and I think I did not examine all drivers yet.
The patchset was smoke-tested on mgag200 by running the fbdev console and Gnome on X11.
