For large and simple repeat actions like this it's a trade off between
the noise of a lot of patches vs easy handling of any future conflicts in
backports.  Given there are 60ish patches if this is broken up, it is a
bit marginal for which approach is preferable.

For more complex changes I would entirely agree that one patch per driver.

So I think I'm fine either way for this particular series.  One patch
per directory, or one patch per driver.
