Wow, actually things are even worse. The latest upstream commit goes
like this:

    treewide: make linux v5.10 a hard requirement for libgpiod
    
    The library now uses v2 of the GPIO uAPI. The new user interface is
    scheduled for release as part of linux v5.10. Linux v5.10-rc1 is now
    tagged so make v5.10 headers a requirement for the build and update
    all tests to check for the correct version.

So a userspace package requires a not-even released Linux kernel
version, without backward compatibility for older kernel versions. This
seems like a really really odd decision from upstream :-/
