[PATCH 2/6] drm: Add drm_simple_encoder_{init,create}()
The simple-encoder helpers initialize an encoder with an empty
implementation. This covers the requirements of most of the existing
DRM drivers. A call to drm_simple_encoder_create() allocates and
initializes an encoder instance, a call to drm_simple_encoder_init()
initializes a pre-allocated instance.

[PATCH v2 0/4] drm: Provide a simple encoder
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 e...

I'd prefer a function call for aesthetic reasons and for not having to
export the drm_simple_encoder_funcs_cleanup. drm_simple_encoder_create()
is also a function and probably cannot be turned into a macro. So having
a function for drm_simple_encoder_init seems consequent.
I guess you want to save a few lines in the implementation of
drm_simple_encoder_init() (?) If so, I'd rather try to share more
internal code among the variou...
