The command sudo make install fails with following output:

Any hints due this problem?

Hi!

Yes, this is ffc8dca. The quickest way is to revert it, for instance by saying

git reset --hard HEAD^

or

git revert ffc8dcabb36a7cbb958769a49d6e12277c14e76b

Differently, you could also upgrade your installed kernel to anything newer than 5.12.
