[PATCH v3 0/3] Split default display handling out from VGA arbiter

[Daniel Axtens]

Hi all,

The merge window is well over by now - is there anything else I can do
to get this series to a mergeable state? I'm not particularly across the
rules for drm-misc, so please let me know if there are things I need to
be doing.

Regards,
Daniel
