The indirection is in setting the encoder functions. Defined in
drivers/gpu/drm/gma500/mdfld_output.h, struct panel_funcs.encoder_funcs
is filled by various Medfield backends with encoder callbacks. But it's
always the same and the encoder_funcs field can be removed. A call to
drm_simple_encoder_init() works for all Medfield code.
Best regards
