The original code is not written in C, so I mistakenly assumed I couldn't
access errno. I checked the documentation and it appears I was wrong - so I
added the necessary code to retrieve errno and... poll() no longer returns
an error.

It may be that I have changed something in the meantime that resolves the
issue, whatever that was, although I cannot find anything relevant in the
git log. Oh well, the libinput driver is working correctly now. If
something comes up, and I can conclusively verify its not my code, I'll
follow up in bugzilla.

Cheers!
