Hi Thomas,
I love your patch! Yet something to improve:
[auto build test ERROR on next-20200305]
[also build test ERROR on v5.6-rc4]
[cannot apply to rockchip/for-next shawnguo/for-next sunxi/sunxi/for-next tegra/for-next linus/master v5.6-rc4 v5.6-rc3 v5.6-rc2]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]

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.
