xserver patches in need of review

[Hans de Goede]

Hi All,

I've recently been working on testing / fixing switchable graphics
support, and specifically the case of an external output which is
only connected to the dgpu while the igpu is the master.

This has resulted in the following patches which need someone
to review them:

https://patchwork.freedesktop.org/patch/89722/
https://patchwork.freedesktop.org/patch/90777/
https://patchwork.freedesktop.org/patch/90982/
https://patchwork.freedesktop.org/patch/90778/
https://patchwork.freedesktop.org/patch/90779/

The last 4 have not only been posted recent-ish, but the first
one has been posted as a v1 (which got not comments) quite a
while ago already, hence this ping and I've thrown in the
other 4 while at it :)

Regards,

Hans
