[PATCH v1 0/3] drm: drm_encoder_init() => drm_encoder_init_funcs()

[Sam Ravnborg <sam@ravnborg.org>]

Thomas Zimmermann had made a nice patch-set that introduced
drm_simple_encoder_init() which is already present in drm-misc-next.

While looking at this it was suddenly obvious to me that
this was functionalty that really should be included in drm_encoder.c
The case where the core could handle the callback is pretty
common and not part of the simple pipe line.

So after some dialog on dri-devel the conclusion was to go for
a change like this:

    drm_encoder_init_funcs() for all users that specified a
    drm_encoder_funcs to extend the functionality.

    drm_encoder_init() for all users that did not
    need to extend the basic functionality with
    drm_encoder_funcs.

A similar approach with a _funcs() prefix is used elsewhere in drm/

This required a rename of the existing users, and
a follow-up patch that moves drm_simple_encoder_init()
to drm_encoder.c

Patches 3 in this set demonstrate the use of drm_encoder_init().
There are many more drivers that can be converted as Thomas
has already demonstrated.

This is all based on work done by Thomas Zimmermann,
I just wanted to implement my suggestion so
we could select the best way forward.

Note: Daniel Vetter has hinted the approach implemented
here smelled like middle-layer.
IMO this is not so, it is just a way to handle cleanup
for the simple cases.
