It'll only make changes for the Notebooks affected. Namely M15T boards for the

Other systems aren't touched.

Unfortunately the kernel fix has been withdrawn with 5.13.8 vanilla (and

A fix for this bug is now staged as part of v5.4.132 to be included in a
kernel update soon (it will be in a 5.11 update around the same time but
not separately tracked there). For 5.13 it should already be included.

Hi all the patch appears to be available!
It is at least present in 5.10.50.
For those on ubuntu 20.04. You can download the kernel here:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10.50/
Make sure to disable secure boot though because the kernel is not
signed.

Many thanks for the feedback!
The patch work comes from Hui Wang, I only posted the easier-to-use .diff. And
I assume, this won't be the final version, as we do too indifferently override
the kernel default behaviour. But IMO it's a great first step in such a short
period of time,

Hi and thanks a lot for your work. I compiled my own custom kernel
version 5.12.9 with the patch you released using Arch Build System,
because of course I use Arch Linux, now the keyboard works well except
for Fn functions, some works and others don't. It's not a problem
No problems Manuel, we will try to change the kernel and will post results.
