What GPIO driver is it using? It's likely that it's not using the
provider API correctly and this change uncovered it, I'd like to take
a look at it and fix it.
How do I find out? The commands below do not return anything.
$ lsmod | grep gpio
$ lspci -nn | grep -i gpio
$ sudo dmesg | grep gpio
[ 5.150955] gpio gpiochip0: gpiochip_add_data_with_key: get_direction failed: -22
[Just these lines match.]
If you have libgpiod-tools installed, you can post the output of
gpiodetect here.
$ sudo gpiodetect
gpiochip0 [INT344B:00] (152 lines)
(In Debian the package name is *gpiod*.)
Kind regards,
Paul
