This commit message is very confusing:
- you mention that you are quoting 2 commits,
- but then you don't quote them but slightly reword the content
- and then, and most of all, you insert in the driver a new timeout of
  250 ms, which seems to not be with the same bases than f567d6ef8606
  where it is mentioned that "Auto-repeat (when a key is held pressed)
  is not affected, because the rate is about 3 times per second, which
  is far less frequent than once in 5 ms." -> 250 ms gets in the roughly
  same range than 3 times per seconds, so some more explanations is
  required

Please also follow Greg's advice and, as you replied in your last message
that didn't made the list (HTML), please resubmit the series with a
clear v3 indicator and a description of changes.

Ideally, I'd like to also have the other plantronics patch you sent
today in the same series, so I know which order I should apply them, in
case one rely on the other.

Cheers,
Benjamin
