6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kenneth Albanowski <kenalba@xxxxxxxxxxxx>
[ Upstream commit 526748b925185e95f1415900ee13c2469d4b64cc ]
The Logitech Casa Touchpad does not reliably send touch release signals
when communicating through the Logitech Bolt wireless-to-USB receiver.
Adjusting the device class to add MT_QUIRK_NOT_SEEN_MEANS_UP to make
sure that no touches become stuck, MT_QUIRK_FORCE_MULTI_INPUT is not
needed, but harmless.
Linux does not have information on which devices are connected to the
Bolt receiver, so we have to enable this for the entire device.
