Hi,

Finally, someone who takes care of the G920!
Note that when I sent my first initial version that Hans reused, I
surely broke it (looking at your patch 3/3), but no one cared to test
it :(

So, you are talking about regressions, and for that I would like to be
able to push the patches to stable.

However, I would need more information:
- patch 3/3 seems simple enough to go in stable, and is clearly a
regression from the recent series. Can you put it in first and add
stable@...r.kernel.org in a CC field (and possibly with a Fixes tag as
well)?
- I am not sure which patch fixes the wheel remains stuck in
autocentering mode. Is it patch 2/3?
- was the "wheel remains stuck in autocentering mode" bug present from
on of the recent patch or was it always there since we introduced
support in hid-logitech-hidpp, but the game would need to unlock the
wheel first?

So all in all, can you:
- drop the first patch and push it in a later series
- re-order the patches: 3/3 then 2/3
- tell me when the wheel is not stuck when the series is applied
(after 3/3 or 2/3), and make a note in the commit message with that
information
- take into account my comments in the first patch you submitted (that
I just sent).

Cheers,
Benjamin
