Yeah, I thought about that but then I had one more patch touching this driver
and if this comes first then that patch should be at 4/5. I was not sure if
that's fine since two patches touching the same driver would be at different
positions in a series.

Anyway, since you said, I'll just move this to 1/5 and other one to 4/5.
