Hi Marco, it should do if it's the same issue. Your choice of actions are to
either:

1) Downgrade to or use kernel 5.12.12 (I don't know which distro you're using,
but it should be available somewhere).
2) Build your own kernel from mainline (currently latest version is 5.13 final)
3) Wait until kernel 5.12.14 or later is available for you (at this time, I
don't think it's been released yet).
4) Download and run a kernel from a 3rd party source that doesn't contain these
commits.

As you're on a laptop (and thus probably on battery power), I would just pick
an earlier kernel for now (option 1). 
If you've got grub for your bootloader (for example), just install an earlier
kernel (or use another one if there's one installed), by choosing it at grub's
menu when you boot up, then once you're logged in and confirm you're not on
5.12.13 (confirm with the command 'uname -a'), remove/uninstall 5.12.13 and
then return things to how you like it.
