As you may know, Melissa is stepping down on her maintainership duties
for VKMS [1].

I want to get the series merged, but, as me and Melissa pointed out last
XDC, we are volunteers. AFAIK VKMS has been maintained by volunteers
since its beginning. We are doing our best to maintain VKMS, but we do
it in our free time.

I need to take some time to review and test this series properly. Then,
I can push it to drm-misc-next.

I appreciate the work you are doing for VKMS. But, apart from adding new
features, we first need to ensure that VKMS is stable. Also, when
reviewing new features, I need to make even more tests to make sure that 
everything is still stable. Therefore, it is a slow process, but I hope
we can start to move forward.
