Thank you everyone for fixing this, I've been following this thread for
the last few weeks and today is the first time I've managed to get it
working.
For any noobs like me that are on Ubuntu this is the guide that I
followed to upgrade to kernel 5.11 and everything works perfectly for
me, both the touchpad and the brightness controls.
Upgrade kernel
Change current directory to /tmp
cd /tmp
Download the latest mainline kernel from 5.11.x branch by copying
and pasting this:
wget -c
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11-rc2/amd64/linux-headers-5.11.0-051100rc2_5.11.0-051100rc2.202101032030_all.deb
wget -c
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11-rc2/amd64/linux-headers-5.11.0-051100rc2-generic_5.11.0-051100rc2.202101032030_amd64.deb
wget -c
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11-rc2/amd64/linux-image-unsigned-5.11.0-051100rc2-generic_5.11.0-051100rc2.202101032030_amd64.deb
wget -c
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11-rc2/amd64/linux-modules-5.11.0-051100rc2-generic_5.11.0-051100rc2.202101032030_amd64.deb
Install new kernel
sudo dpkg -i *.deb
Reboot the system
sudo shutdown -r now
Update packages list
sudo apt-get update
Upgrade packages
sudo apt-get upgrade
Reboot the system if needed
sudo shutdown -r now
Check the OS distro
lsb_release -a
Check kernel version
uname -r
That's it, now you should be running on the Linux Kernel 5.11rc2

Thanks to everyone for their hard work, sorry for posting this noob
guide here but it took me weeks to figure out an easy way to do it
(patching was beyond my abilities).
