If you're refering to the build bot warning I got, too, then the problem
is just a missing #include and the problem existed already before e.g.
for gpiod_get_value with the .config used by the build bot.

In reply to this mail I'll send a fixup patch for the missing include
and a reworked version of my patch that fixes the reference leak pointed
out by Krzysztof Kozlowski.

Best regards
Uwe
