Re: [PATCH 6/7] drm/mediatek: mtk_dsi: Use the drm_panel_bridge API

[Sam Ravnborg <sam@ravnborg.org>]

Hi Enric.

Just a "drive-by" comment.
I browsed all the patches - and nothing jumped at me.
But then I did not follow all the changes.

This assignment of panel->connector_type is wrong.
We should let the panel tell the type of connector.

And if the panel fails to do so - then fix it in the panel.

One day, when I get sufficiently bored/motivated I plan to go through
all panels to make sure they all update connector_type.
