The combo on the Miix 630 has an ACPI id of QTEC0001, which is not claimed by the elan_i2c driver, so key on that similar to what was done for the Toshiba Click Mini.

Currently, both use whitelists, which results in valid devices being unhandled by default, when they should not be rejected by hid-quirks. This is quickly becoming an issue. Since elan_i2c has a maintained whitelist of what devices it will handle, which is now in a header file that hid-quirks can access, use that to implement a blacklist in hid-quirks so that only the devices that need to be handled by elan_i2c get rejected by hid-quirks, and everything else is handled by default.

Currently, both use whitelists, which results in valid devices being unhandled by default, when they should not be rejected by hid-quirks. This is quickly becoming an issue. Since elan_i2c has a maintained whitelist of what devices it will handle, which is now in a header file that hid-quirks can access, use that to implement a blacklist in hid-quirks so that only the devices that need to be handled by elan_i2c get rejected by hid-quirks, and everything else is handled by default.
