[PATCH] drm/rockchip: Open-code drm_simple_encoder_init()

[PATCH] drm/rockchip: Open-code drm_simple_encoder_init()

[x]

From: Favilances Noir <favilances@proton.me>

drm_simple_encoder_init() wraps drm_encoder_init().

It uses drm_encoder_cleanup() as the encoder destroy callback.

Add driver-local drm_encoder_funcs and call drm_encoder_init() directly.

This is a TODO cleanup towards removing drm_simple_encoder_init().

No functional change intended.
