I do not know what you mean by "issues in linux-next" (I assume you mean
when Shawn sends the patches to linux-next in preparation for v4.21); we
have not planned any other PCI pull request for v4.20-rc1 material.

I can ACK it if Shawn wants to pull it, it may take a while to see it
in -next if it has to go through the PCI tree, I think it is better
to queue the series without splitting the patches across multiple
channels though.
