Why is libgpiod is corrupting my filesystem?

Question

I have an OpenWRT system (Intel) where I have to control some GPIOS (it87). I would like to update from the classic sysfs approach (which works fine, but is being deprecated) to the new chardev, using libgpiod.

However, when I use the gpiod-tools (gpioget for instance), after a while using it, random files with random names (but all of them look like output console sentences) starts to create on / directory. Let me show you an example (this is after 1 hour uptime, only blue folders should be there)

This happens with OpenWRT 21 & 22, and with kernel 5.4 & 5.10.154. I really don't know why it is happening.

I tried tweaking some kernel paremeters regarding GPIO, my current cfg is as follows:

I tried also enabling both (sysfs & chardev), no luck.

What I'm missing? Could be something in other kernel cfg section?

Thank you! Any help would be really appreciated!
