Hi Greg. Would be great if you could pick up 690eb7dec72a ("HID:
logitech: Disable hi-res scrolling on USB") for the next 6.1.y release,
as it's fixing a regression I saw multiple people report.
The commit (see below) that was recently merged to mainline and has a
proper stable "Cc: <stable@...>" tag, so I guess you scripts will at
some point pick it up automatically. But I noticed you updated the
stable queue and hour ago and this patch afaics is not in it yet
(despite some other patches being in it that were merged later), so I
thought: just to be sure send a quick heads up.
Ciao, Thorsten
