commit 1796f808e4bb ("HID: i2c-hid: acpi: Stop setting wakeup_capable")
changed the policy such that I2C touchpads may be able to wake up the
system by default if the system is configured as such.

However for some devices there is a bug, that is causing the touchpad to
instantly wake up the device again once it gets deactivated. The root cause
is still under investigation:

Bart, I'm fine if it goes directly via your tree, or I can send it in usual
bundle of fixes after rc1 (however it seems this deserves to make v6.2).
Actually we have yet another little fix. So maybe I can create a tagged bundle.
Perhaps v4 will be the best option here.
on it

Just realized i did not add cc stable:

It is required for 6.1 also.
We have at least the following options:
- you can send specific request for stable after it becomes a part of upstream
- you can send a v4 with it

To workaround this problem for the time being, introduce a quirk for this
model that will prevent the wakeup capability for being set for GPIO 16.
