[v2] HID: multitouch: Add quirk for HONOR MagicBook Art 14 touchpad

[PATCH v2] HID: multitouch: Add quirk for HONOR MagicBook Art 14 touchpad

Posted by WangYuli 1 month, 3 weeks ago

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.

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.
