[Bug 1887190] Re: MSFT Touchpad not working on Lenovo Legion-5 15ARH05

Thank you @Coiby Xu (coiby) and Von (straeker) and everyone else for
your work. The standalone patch #217 is working perfectly on a fresh
Ubuntu 20.10, installed with secure boot (5.8.0-25-generic). No suspend
problems.

@PEDRO PORTO BUARQUE DE GUSMAO (pedropgusmao), Piotr Tomaszewski
(nfm886): To make the module work under secure boot, the module needs to
be signed first before inserting. Just skip the signing if you don't use
secure boot but don't want to rebuild the whole kernel:

- Download the standalone module from #217

- Install "build-essential" package (if it is missing) which is needed to build the module:
$ sudo apt install build-essential

- "make" the module as in #211

- Sign the module before inserting:
$ kmodsign sha512 \
/var/lib/shim-signed/mok/MOK.priv \
/var/lib/shim-signed/mok/MOK.der \
i2c-hid.ko

- Insert and copy the module and update grub and initramfs as in #228

Bug description:
Hello

The MSFT touchpad of this Lenovo Legion-5 15ARH05 laptop is not reacting at all (pointer and click never move when touchpad is touched). This has been reported by other users in various websites, with various linux systems including other Ubuntu systems, but I saw no launchpad bug so I post one. Example of websites covering the issue :
- https://askubuntu.com/questions/1253830/lenovo-legion-5-touchpad (exactly the same laptop)
- https://www.linux.org/threads/lenovo-legion-5-touchpad.29536/ (similar laptop)

xinput indentifies it as MSFT0001:00 04F3:3140

Thanks a lot for your time. It does not help, but I can confirm what
was reported on askubuntu by another user : the touchpad does work on
Windows.
