Hi!
Sorry for the delay.

I don't think you need to escape ' with \.

I'd do if (!fwnode_property_present()) return; in both occasions, to
save an indentation level; but that's nitpicking.

Unlike snprintf(), strncpy() does not guarantee NULL termination.
I did not check the shell script.
With that fixed,
