I guess, in this case it's fine to leave it as is [in this series].
The series has been reviewed now.

But [for me typically], I delay doing a review if a patch-series is
longer than 4-5 patches. And I think some reviewers may do the same.
So, if I want more people to review/look at my code, I try to make
things as easy to review, as possible.
And one way, is to definitely keep things decoupled.
If one patch can be independent of another [for the same driver/code],
I send them as separate patches.

This [of course], is a preference. Some reviewers don't mind longer
series [than 4-5 patches].
