Hi Jakob, thanks for the response.
Tried it, got many error messages while trying to disassemble the
original acpi table.

Bug description:
[SRU Justification]
[Impact]
Touchpad function unavailable on some platforms with new ELAN touchpad
HIDs.
[Fix]
https://lore.kernel.org/linux-input/000201d5a8bd$9fead3f0$dfc07bd0$@emc.com.tw/
required to match these currently unsupported IDs.
[Test Case]
1. check if platform is affected, e.g. with ELAN0634:
$ sudo acpidump | grep -C3 ELAN

2A0C0: 13 0A 10 F7 F6 DF 3C 67 42 55 45 AD 05 B3 0A 3D ......<gBUE....=
2. check if touchpad then appear in /proc/bus/input/devices when
applied.
[Regression Potential]
Low. Only add new IDs for currently unsupported platforms.
========== Original Bug Description ==========
The Elan touchpad on my Lenovo Thinkbook isn't being detected, and
hence isn't working.
`sudo acpidump | grep -C3 ELAN` gives me the device's ACPI id:
```bash
ghosthawkzero@EchelonV:~$ sudo acpidump | grep -C3 ELAN

ghosthawkzero@EchelonV:~$
```
Have attached the content from /proc/bus/input/devices.
**EXPECTED** - touchpad to work
**WHAT IS HAPPENING** - touchpad not detected and touchpad not
working.
