Remove the ACPI-HID + DMI-id deny-lists for touchpad_ctrl_via_ec and instead make it a module option which defaults to false. The touchpad sysfs attribute allowing directly writing VPCCMD_W_TOUCHPAD from userspace has been leading to a lot of bug-reports / patches adding both ACPI HID + dmi-id based deny-lists for it which then need to be expanded all the time going forward leading to a high maintenance load. At the same time the touchpad sysfs attribute is not a standard Linux userspace API. So it is not used in standard desktop-enviroments, instead it is only used in the following 2 rare circumstances: 1. Ideapad specific control-panel like applets 2. Custom scripts written by users For 1. these applets need to already deal with the touchpad sysfs attr sometimes not being there because of the existing deny lists so hiding it be default should not cause an issue; and most desktop environments already have a touchpad-disable option in their native control-panel, so having an ideapad specific toggle for this is not necessary. For 2. since these users are already customizing their systems they can add the module option if they want to keep using the touchpad sysfs attribute.
