You're right that many people have added far more significant changes
than this without adding a copyright string, so we shouldn't add this
one now.

In general, though, I'd say that the rule is that you may (but are not
required to) add a copyright string if your change is reasonably large
and non-obvious/non-boilerplate.  I don't think the copyright string
means anything -- copyright is implicit in the authorship history which
Git preserves -- but I'm not a lawyer.  Having your name in the
copyright string may make enforcing the GPL for that driver slightly
easier for you, so for that reason I'm glad Pierre added himself.

Thanks,

- Chris.
