[PATCH] HID: multitouch: Add quirk for HONOR MagicBook Art 14 touchpad

Posted by WangYuli 2 months ago

[Problem]
It sometimes after reboot change output from Touchpad to Mouse,
evtest show it output from "TOPS0102:00 35CC:0104 Touchpad"
to "TOPS0102:00 35CC:0104 Mouse",and it works as A mouse.

[Solution]
Like GLO-GXXX,As a workaround, it is possible to call
MT_QUIRK_FORCE_GET_FEATURE to force set feature in mt_set_input_mode
for such special touchpad device.

Hi,

few formatting issues, but other than that patch looks good:

Not sure this Link adds anything: it's a personal fork of libinput, so
we don't really care.
I think with the libinput issue from above we have enough information to
relate to the MR linked to this commit, so please just drop the second
link
