drmm_plain_encoder_alloc - Allocate and initialize an encoder @dev: drm device @funcs: callbacks for this encoder (optional) @encoder_type: user visible type of the encoder This is a simplified version of drmm_encoder_alloc(), which only allocates and returns a struct drm_encoder instance, with no subclassing. Returns: Pointer to the new drm_encoder struct, or ERR_PTR on failure.
