Hmm, the hantro driver will be unstaged either this week or (hopefully)
very early on in the next cycle. So I think you should no longer consider
hantro as a staging driver but as a regular mainline driver.

This series definitely won't make the 5.20 cut, so I think it makes more
sense to get this right before merging it.
