The code responsible for creating the IN_FORMATS blob is broken when the driver doesn't provide a .format_mod_supported() hook. It just copies in the format list, but leaves all the modifier information zeroed. That would indicate (in a very silly way) that there are in fact no supported format+modifier combinations. That is utter nonsense.
Should we WARN_ON when the driver enables allow_fb_modifiers but doesn't populate format_mod_supported?
