Thanks for the report and sorry for the delay in responding. Looks
like gpiod_get_array_value_cansleep initializes values. But we do
have wrong defines here, see the patch belwo.

Not sure if that is enough to fix the warning here though? I'm not
seeing the warning here with gcc-7.3.0 binutils-2.30.

Regards,

Tony
