I presume Linus is busy or otherwise indisposed.

So I guess we have two options here:

a) Cong Yang can post any relevant fixes to the existing "monolithic"
panel driver so that we can get them landed and at least get things
fixed.

- or -

b) Cong Yang could take over all or some of Linus's series and post
new versions of it, addressing feedback.

I would tend to say we should go with "a)" because I think Linus needs
to be involved in some of the cleanup discussions.
